Species Overview
The Green Moscow Guppy (Poecilia reticulata) is a selectively bred fancy guppy developed for the deep, reflective green coloration characteristic of the Green Moscow strain. Rather than relying on contrasting spots or complex tail patterns, Moscow-type guppies are prized for extensive coloration that can continue across much of the body and into the fins, creating a more uniform appearance than many patterned fancy guppy strains.
Males typically develop the strongest green coloration and more elaborate ornamental finnage, with their appearance shifting between green, blue-green, and metallic tones as the fish moves under different lighting. Females grow larger and develop fuller bodies, with coloration generally more restrained than mature males. Like other domestic guppies, Green Moscow Guppies are active, social livebearers that spend much of the day swimming, displaying, interacting, and foraging through the upper and middle portions of the aquarium.
Our Green Moscow Guppies are Bred by Aquatic Arts through our own guppy breeding program. Raising this strain ourselves gives our team direct involvement from breeding and early development through grow-out, conditioning, and preparation for sale. Their distinctive Moscow-type coloration, peaceful temperament, manageable adult size, and constant activity make them an excellent choice for planted displays, appropriately planned community aquariums, and selective guppy breeding projects.

Aquatic Arts Tip
Because our Green Moscow Guppies are Bred by Aquatic Arts, we are directly involved in the conditions under which the line is bred and raised. Once a fish reaches its new aquarium, long-term success depends on maintaining stable water chemistry, appropriate mineral content, good nutrition, and consistent aquarium maintenance.
Recommended Water Parameters & Aquarium Requirements
Water Parameters
Temperature: 72–82°F (22–28°C)
pH: 7.0–8.2
GH: 8–18 dGH
KH: 4–12 dKH
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: Ideally maintained below 20 ppm through appropriate stocking, feeding, filtration, and regular water changes
Aquarium Requirements
Minimum Aquarium Size: 10 gallons. Larger aquariums provide greater water stability and additional swimming space for groups, community setups, and growing populations of fry.
Filtration: Use reliable biological and mechanical filtration appropriate for the aquarium's size and stocking level. Sponge filters are particularly useful in breeding and fry-rearing aquariums because they provide biological filtration without a strong intake that can endanger newborn fry.
Water Flow: Low to moderate. Green Moscow Guppies are active swimmers but do not require strong current, particularly males carrying developed ornamental fins.
Oxygenation: Maintain good gas exchange through appropriate filtration, surface movement, or supplemental aeration when necessary.
Aquarium Maturity: Keep Green Moscow Guppies only in a fully cycled aquarium with established biological filtration. Guppies should never be used to cycle a new aquarium.
Plants: Highly recommended. Live plants provide cover, natural grazing surfaces, visual barriers, and refuge for newborn fry while adding biological complexity to the aquarium.
Lighting: Low to moderate lighting is sufficient for the fish themselves. Choose lighting intensity primarily according to the requirements of the live plants being maintained.
Aquatic Arts Tip
Our Bred by Aquatic Arts Green Moscow Guppies are raised in stable, mineral-rich freshwater. When moving them into a new aquarium, focus on providing suitable and consistent conditions rather than trying to duplicate an exact set of numbers. Repeatedly adjusting pH or hardness can create more stress than maintaining stable water that already falls within an appropriate range.
The Green Moscow Guppy (Poecilia reticulata) is a selectively bred aquarium strain and does not occur naturally in the wild. Our Green Moscow Guppies are Bred by Aquatic Arts, while the wild species from which domestic fancy guppies originate is native to northeastern South America and parts of the Caribbean.
Wild Poecilia reticulata inhabit a broad range of freshwater environments, including streams, springs, pools, canals, and vegetated margins of larger waterways. Many populations live around aquatic vegetation, submerged roots, algae-covered surfaces, and shallow areas with slower current. These habitats provide feeding opportunities from algae, biofilm, microorganisms, insect larvae, and other small invertebrates while vegetation and submerged structure offer refuge for juveniles.
There is no wild Green Moscow habitat for an aquarist to reproduce. Instead, use the functional characteristics of the species' ancestral environments as a guide: stable mineral-rich water, abundant live plants and grazing surfaces, areas of cover, and open water where these active fish can swim and display.
The Green Moscow Guppy (Poecilia reticulata) benefits from an aquascape that combines dense planted areas with open swimming space. Taller plants and hardscape positioned along the back and sides create shelter and visual breaks while leaving the upper and middle portions of the aquarium open for swimming, displaying, and courtship.
- Live Plants: Amazon Swords, Water Sprite, Bacopa, Cryptocoryne, Java Fern, and Anubias provide a mixture of broad leaves, vertical growth, and sheltered areas without requiring the entire aquarium to be densely planted.
- Floating Plants: Amazon Frogbit, Salvinia, Red Root Floaters, and Dwarf Water Lettuce create overhead cover and hanging root systems that provide refuge for newborn fry. Keep portions of the surface open for gas exchange and unobstructed swimming.
- Mosses and Fry Cover: Java Moss, Christmas Moss, Subwassertang, and Guppy Grass create dense structure for newborn guppies while providing extensive surfaces for biofilm and microorganisms.
- Driftwood: Manzanita, Spider Wood, and Malaysian Driftwood add natural structure and attachment points for Anubias, Java Fern, and mosses. Arrange wood so that developed fins have clear swimming routes around the hardscape.
- Rockwork: Smooth river stones, rounded cobbles, and other aquarium-safe rock can anchor planted areas and create additional visual structure. Avoid sharp or abrasive rockwork around long-finned males.
- Substrate: Sand, fine gravel, and planted aquarium substrates are all suitable. Green Moscow Guppies have no specialized substrate requirement, so substrate choice should primarily support the plants and aquascaping style being used.
Aquatic Arts Tip
The reflective coloration of a Green Moscow Guppy can look noticeably different as the fish changes position relative to the aquarium lighting. Darker natural backgrounds, wood, and plants with contrasting leaf colors can help the green and blue-green tones remain visually distinct without using artificial lighting tricks or color enhancement to misrepresent the fish.
The Green Moscow Guppy (Poecilia reticulata) is an omnivore and benefits from a varied diet containing both animal- and plant-based foods. Guppies naturally spend much of the day investigating surfaces and the water column for algae, biofilm, microorganisms, small invertebrates, and insect larvae, so dietary variety is more useful than relying on a single food exclusively.
Staple Diet: Offer a high-quality tropical flake or appropriately sized micro pellet as the nutritional foundation. Rotating quality prepared foods can provide a broader range of ingredients while keeping everyday feeding straightforward.
Live Foods: Daphnia, Moina, baby brine shrimp, Grindal Worms, and other appropriately sized live foods are excellent supplements. Live foods encourage natural feeding behavior and are especially useful when conditioning breeding adults or supporting growing juveniles.
Frozen Foods: Frozen brine shrimp, Daphnia, Cyclops, and occasional small portions of bloodworms can be incorporated into the feeding rotation. Frozen foods should supplement a balanced diet rather than become the only foods offered.
Plant-Based Foods: Spirulina flakes and other quality prepared foods containing algae or plant ingredients help provide the plant component of a balanced omnivorous diet.
Natural Grazing: Mature planted aquariums provide algae, biofilm, and microorganisms that Green Moscow Guppies will investigate throughout the day. Natural grazing adds enrichment and dietary variety but does not replace regular feeding.
Feeding Frequency: Feed adult Green Moscow Guppies one or two small meals per day, offering only what they can consume promptly. Fry and growing juveniles benefit from smaller, more frequent meals when filtration and water changes can support the additional feeding.
Aquatic Arts Tip
Feed for health and condition, not for a particular shade of green. Genetics establish the Green Moscow Guppy's underlying color potential, while good nutrition supports healthy growth, fin development, body condition, and natural color expression. Because Moscow coloration can appear greener, blue-green, or darker depending on lighting and viewing angle, a change in how the fish looks is not automatically a dietary problem.
The Green Moscow Guppy (Poecilia reticulata) is a peaceful community fish that does best with non-aggressive species sharing its preference for stable, mineral-rich water. Compatibility should consider water chemistry, temperature, adult size, activity level, swimming zone, and fin-nipping behavior rather than relying only on a general “peaceful” label.
Other Livebearers: Platies (Xiphophorus maculatus), Variatus Platies (Xiphophorus variatus), and appropriately housed mollies (Poecilia spp.) generally share compatible water preferences with Green Moscow Guppies. Endler's Livebearers (Poecilia wingei) can also thrive under similar conditions, but guppies and Endlers can hybridize and should not be combined when preserving either breeding line is important.
Small Schooling Fish: Pristella Tetras (Pristella maxillaris), Black Neon Tetras (Hyphessobrycon herbertaxelrodi), and Glowlight Danios (Danio choprae) can be considered where the aquarium provides an appropriate overlap in temperature, water chemistry, and swimming space. Schooling species should always be maintained in suitable groups rather than added individually.
Corydoras: Peppered Corydoras (Corydoras paleatus), Panda Corydoras (Corydoras panda), and Pygmy Corydoras (Corydoras pygmaeus) can provide peaceful activity along the bottom of the aquarium when their individual temperature and water requirements overlap with the guppy setup. Corydoras should be maintained in proper social groups with adequate bottom area.
Small Plecos: Bristlenose Plecos (Ancistrus spp.), Clown Plecos (Panaqolus maccus), and appropriately housed Rubber Lip Plecos (Chaetostoma spp.) are generally peaceful toward guppies. Each still requires species-appropriate food, space, and habitat rather than being added simply for algae control.
Freshwater Shrimp: Adult Neocaridina Shrimp, Amano Shrimp, Bamboo Shrimp, and Vampire Shrimp can coexist with Green Moscow Guppies when their respective aquarium requirements are met. Very small shrimplets remain vulnerable to opportunistic feeding.
Freshwater Snails: Nerite Snails, Mystery Snails (Pomacea diffusa), Ramshorn Snails, and Malaysian Trumpet Snails are generally compatible. The mineral-rich water preferred by Green Moscow Guppies can also support healthy shell development in many freshwater snails.
Tank Mates We Would Avoid
Avoid persistent fin-nipping species such as Tiger Barbs (Puntigrus tetrazona) and Serpae Tetras (Hyphessobrycon eques), as well as large predatory fish, aggressive cichlids, and other species capable of harassing or consuming guppies.
Fish that require consistently very soft, acidic water can also be poor long-term companions even when temperament is not a concern. Two species being peaceful does not automatically mean their husbandry requirements are compatible.
Aquatic Arts Tip
A community aquarium works best when its inhabitants are selected around a shared range of conditions rather than assembled one fish at a time. Start with the Green Moscow Guppy's water requirements, then choose companions whose temperature, hardness, adult size, activity level, and social needs fit within the same aquarium.
Shrimp Safe
Yes, With Adult Shrimp
The Green Moscow Guppy (Poecilia reticulata) is generally considered safe to keep with adult freshwater shrimp. Adult Neocaridina Shrimp (Neocaridina davidi), Amano Shrimp (Caridina multidentata), Bamboo Shrimp, and Vampire Shrimp can typically coexist well with Green Moscow Guppies in an appropriately planned planted aquarium.
Very small shrimplets may occasionally be eaten if encountered, as is possible with nearly any small community fish. Dense Java Moss, Guppy Grass, Subwassertang, floating plant roots, driftwood, and other fine structure provide young shrimp with places to retreat while increasing the surfaces available for biofilm and microorganisms to develop.
For aquarists who want adult shrimp as part of a planted community display, Green Moscow Guppies are a good option. If maximizing shrimp reproduction and the number of surviving shrimplets is the primary goal, a dedicated shrimp aquarium remains the better choice.
Breeding Difficulty: Easy
Reproduction Type: Livebearer
Gestation: Typically about 3–4 weeks
Brood Size: Variable. Young females may produce relatively small broods, while larger mature females can give birth to several dozen fry at one time.
The Green Moscow Guppy (Poecilia reticulata) is a livebearer, meaning females give birth to fully formed, free-swimming fry rather than laying eggs. Green Moscow Guppies generally reproduce readily once sexually mature when maintained in stable water and provided with a varied, nutritious diet.
Breeding Groups: Approximately one male for every two or three females is a practical starting point for a mixed-sex breeding group. Male guppies court frequently, and maintaining multiple females helps distribute that attention rather than concentrating it on a single fish.
Gestation and Birth: Female Green Moscow Guppies typically carry developing fry for approximately three to four weeks, although timing varies with temperature, age, condition, and the individual female. Female guppies can store sperm after mating and may produce multiple later broods without mating again.
Protecting Fry: Green Moscow Guppies provide no parental care, and adults may eat newborn fry they encounter. Dense Java Moss, Guppy Grass, Subwassertang, Water Sprite, and floating plant roots provide immediate refuge. Aquarists seeking maximum fry survival can raise the young separately from the adults.
Feeding Fry: Newly born Green Moscow Guppies can eat newly hatched baby brine shrimp, microworms, finely crushed quality flakes, and appropriately sized fry foods. Several small meals throughout the day support juvenile growth when filtration and water changes keep pace with the additional feeding.
Maintaining the Green Moscow Line: Because our Green Moscow Guppies are Bred by Aquatic Arts, maintaining the recognizable characteristics of the line requires selective breeding rather than simply allowing every offspring to reproduce. Keep Green Moscow Guppies separate from other guppy strains and Endler's Livebearers (Poecilia wingei) when preserving the line, and select future breeders based on the coloration, body quality, finnage, health, and other characteristics being maintained in the breeding program.
Aquatic Arts Tip
Breeding guppies is easy; keeping a recognizable line consistent takes selection. If maintaining Green Moscow characteristics is the goal, keep breeding records and evaluate offspring as they mature rather than choosing future breeders solely because they developed color first.
What is a Green Moscow Guppy?
The Green Moscow Guppy (Poecilia reticulata) is a selectively bred fancy guppy developed for extensive green to blue-green coloration across the body and fins. Green Moscow Guppies are domestic aquarium strains rather than a naturally occurring wild form of Poecilia reticulata.
What does “Moscow” mean in Green Moscow Guppy?
In fancy guppies, Moscow refers to a recognized strain tradition associated with extensive body coloration that often continues into the fins. Moscow is a breeding-strain designation rather than a separate species or geographic origin for the individual fish.
Are Green Moscow Guppies actually from Moscow?
No. The name Green Moscow Guppy refers to the Moscow strain tradition in the fancy guppy hobby. It does not mean the fish being sold were raised in Moscow or that wild guppies naturally occur there. Our Green Moscow Guppies are Bred by Aquatic Arts.
Is a Green Moscow Guppy a different species from other guppies?
No. Green Moscow Guppies are Poecilia reticulata, the same species as other domestic fancy guppies. Moscow, Dragon, Mosaic, Cobra, Grass, and similar names describe selectively bred strains or characteristics rather than separate species.
Are Green Moscow Guppies found in the wild?
No. Green Moscow Guppies are selectively bred aquarium fish. Wild Poecilia reticulata, the species from which domestic fancy guppies originate, is native to northeastern South America and parts of the Caribbean.
What does Bred by Aquatic Arts mean for Green Moscow Guppies?
Our Green Moscow Guppies are produced through the Aquatic Arts breeding program. Our team is directly involved in breeding, raising, grow-out, observation, conditioning, and preparing these fish for their future aquariums.
Are Green Moscow Guppies good for beginners?
Yes. Green Moscow Guppies are relatively easy to maintain in a fully cycled aquarium with stable water chemistry, adequate mineral content, appropriate filtration, and a varied diet. Their adaptability does not mean they should be exposed to poor water quality or used to cycle a new aquarium.
How large do Green Moscow Guppies get?
Male Green Moscow Guppies typically reach approximately 1.5–2 inches, while females commonly reach approximately 2–2.5 inches. Females generally develop larger, fuller bodies, while males typically develop more elaborate ornamental finnage.
How long do Green Moscow Guppies live?
Green Moscow Guppies commonly live approximately 2–3 years. Genetics, temperature, nutrition, reproductive demands, water quality, and overall husbandry can influence individual lifespan.
How can you tell a male Green Moscow Guppy from a female?
Male Green Moscow Guppies are generally smaller and develop stronger coloration and more elaborate fins. Mature males also possess a modified anal fin called a gonopodium. Females are usually larger and fuller-bodied and retain a fan-shaped anal fin.
Why does my Green Moscow Guppy sometimes look blue?
The reflective coloration of a Green Moscow Guppy can appear green, blue-green, turquoise, or darker depending on lighting, viewing angle, background, and the individual fish. A shift in apparent color as the fish moves does not necessarily mean its actual coloration is changing.
Are all Green Moscow Guppies exactly the same shade of green?
No. Individual Green Moscow Guppies can differ in shade, intensity, coverage, and how their coloration appears under different lighting. Selective breeding can produce recognizable strain characteristics without making every individual visually identical.
Do Green Moscow Guppies need to be kept in groups?
Green Moscow Guppies are social and are generally best maintained with other compatible guppies rather than as solitary display fish. Guppies interact, court, display, and forage together, but they do not form the tightly coordinated schools characteristic of many tetras, rasboras, and danios.
Can I keep only male Green Moscow Guppies?
Yes. An all-male Green Moscow Guppy aquarium can provide a colorful display without producing fry. Males may still display toward and occasionally chase one another, so provide adequate space and visual structure.
Can I keep only female Green Moscow Guppies?
Yes, but a newly acquired female may already have mated. Female guppies can store sperm and produce multiple later broods, so an aquarium containing only females can still produce fry.
What male-to-female ratio is best for Green Moscow Guppies?
For a mixed-sex breeding group, approximately one male for every two or three females is a practical starting point. This helps distribute the frequent courtship behavior of male guppies among multiple females.
What size aquarium does a Green Moscow Guppy need?
We recommend a minimum aquarium size of 10 gallons for Green Moscow Guppies. Larger aquariums provide greater water stability and additional room for groups, community fish, and growing populations of fry.
What water parameters are best for Green Moscow Guppies?
Green Moscow Guppies do well at approximately 72–82°F (22–28°C), pH 7.0–8.2, GH 8–18 dGH, and KH 4–12 dKH. Stable conditions within an appropriate range are more important than repeatedly adjusting the aquarium to achieve one exact number.
Do Green Moscow Guppies need hard water?
Green Moscow Guppies generally perform best in freshwater containing a meaningful amount of dissolved minerals rather than extremely soft, poorly buffered water. Appropriate GH provides important minerals, while KH contributes to buffering and pH stability.
Do Green Moscow Guppies need live plants?
Live plants are not mandatory, but they are highly beneficial. Plants provide Green Moscow Guppies with cover, visual barriers, grazing surfaces, and refuge for newborn fry while increasing the structural complexity of the aquarium.
What do Green Moscow Guppies eat?
Green Moscow Guppies are omnivores. Offer quality tropical flakes or micro pellets supplemented with foods such as Daphnia, Moina, baby brine shrimp, Cyclops, Grindal Worms, and quality plant-based foods.
Will special food make a Green Moscow Guppy greener?
Food cannot create Green Moscow genetics that the fish does not possess. A balanced diet supports healthy development and natural color expression, while the apparent shade of a Green Moscow Guppy is also strongly affected by lighting, viewing angle, background, age, and individual genetics.
Are Green Moscow Guppies peaceful?
Yes. Green Moscow Guppies are generally peaceful community fish. Some displaying, courtship, and chasing between guppies is normal, but persistent harassment should be addressed through appropriate group composition, aquarium size, and habitat structure.
Are Green Moscow Guppies fin nippers?
Green Moscow Guppies are not generally considered persistent fin nippers. Their developed ornamental fins can instead make them targets for species known for repeated fin-nipping behavior.
Can Green Moscow Guppies live with shrimp?
Yes. Green Moscow Guppies can generally coexist with adult Neocaridina Shrimp, Amano Shrimp, Bamboo Shrimp, and Vampire Shrimp when their respective water requirements are met. Very small shrimplets may occasionally be eaten if encountered.
Can Green Moscow Guppies live with snails?
Yes. Nerite Snails, Mystery Snails, Ramshorn Snails, and Malaysian Trumpet Snails are generally compatible with Green Moscow Guppies when the aquarium meets the requirements of both animals.
Can Green Moscow Guppies live with other guppy strains?
Yes. Different domestic guppy strains share similar basic husbandry and can generally live together. However, male and female guppies from different strains can interbreed, so separate strains when maintaining the Green Moscow line is important.
Can Green Moscow Guppies live with Endler's Livebearers?
Green Moscow Guppies and Endler's Livebearers (Poecilia wingei) can live under similar aquarium conditions, but guppies and Endlers can hybridize. We would not combine them in a breeding aquarium intended to preserve either line.
What is the difference between a Green Moscow Guppy and a Blue Moscow Guppy?
Green Moscow and Blue Moscow Guppies belong to Moscow-type breeding lines but are selected for different color expression. Green Moscow Guppies emphasize green to blue-green coloration, while Blue Moscow Guppies emphasize deeper blue coloration. Lighting can influence how both strains appear, so some visual overlap is possible.
What is the difference between a Green Moscow Guppy and a Purple Moscow Guppy?
Green Moscow Guppies are selected for green to blue-green coloration, while Purple Moscow Guppies emphasize purple, violet, or related darker coloration. Both are domestic Poecilia reticulata and have essentially the same fundamental care requirements.
What is the difference between a Green Moscow Guppy and a Black Moscow Guppy?
Green Moscow Guppies are selected for extensive reflective green coloration, while Black Moscow Guppies are selected toward much darker overall pigmentation. Both belong to Moscow-type fancy guppy breeding traditions but represent different color lines.
What is the difference between a Green Moscow Guppy and a Full Green Guppy?
The names can describe visually similar fish, but Moscow refers to a particular fancy-guppy breeding tradition, while a general name such as Full Green primarily describes overall coloration. Naming conventions can vary among breeders, so the strain name alone should not be treated as proof that two independently bred lines have identical genetics.
What is the difference between a Green Moscow Guppy and a Green Cobra Guppy?
A Green Cobra Guppy is associated with Cobra or Snakeskin-style reticulated body patterning, while a Green Moscow Guppy is selected for the more extensive body coloration associated with Moscow-type lines. Both are selectively bred forms of Poecilia reticulata.
What is the difference between a Green Moscow Guppy and a Green Dragon Guppy?
Green Dragon Guppies are selected around Dragon-type pattern and color characteristics, while Green Moscow Guppies are associated with the more extensive body coloration characteristic of Moscow-type lines. Dragon and Moscow are fancy-guppy breeding designations rather than separate species.
What is the difference between Moscow, Dragon, Mosaic, Cobra, and Grass guppies?
These terms describe different fancy guppy breeding traditions, patterns, colors, or strain characteristics rather than different species. Moscow is associated with extensive body coloration, Mosaic with patterned finnage, Cobra or Snakeskin with reticulated body patterning, and Grass with fine spotting in the fins. Dragon is used for lines selected for a distinctive contrasting appearance, although exact terminology and expression can vary among breeders.
Can Green Moscow Guppies breed with other Moscow colors?
Yes. Green Moscow Guppies can reproduce with Blue Moscow, Purple Moscow, Black Moscow, and other domestic guppies because they are all Poecilia reticulata. Crossing color lines can produce variable offspring and should be avoided when maintaining a consistent Green Moscow breeding line.
What happens if I breed a Green Moscow Guppy with another guppy strain?
The resulting offspring can display mixtures of coloration, pattern, finnage, and other inherited characteristics. Later generations can become even more variable, so controlled pairings and breeder selection are necessary when maintaining a recognizable Green Moscow line.
How often do Green Moscow Guppies have fry?
Female Green Moscow Guppies can typically produce a brood approximately every three to four weeks under suitable conditions. Timing varies with temperature, age, nutrition, reproductive condition, and the individual female.
Can a female Green Moscow Guppy have fry without a male present?
Yes. Female guppies can store sperm from previous matings and use it for later broods. A female Green Moscow Guppy introduced to an aquarium without males may therefore still produce fry.
Do Green Moscow Guppies eat their fry?
Adult Green Moscow Guppies may eat newborn fry they encounter because guppies provide no parental care. Dense mosses, Guppy Grass, Water Sprite, and floating plant roots provide refuge, while separating fry from adults provides greater survival when maximizing offspring is the goal.
Why is my Green Moscow Guppy losing color?
Reduced coloration can be associated with stress, poor water quality, inappropriate temperature or water chemistry, illness, inadequate nutrition, social stress, age, or individual genetics. First evaluate the fish's health and aquarium conditions rather than immediately assuming that a color-enhancing food is needed.
Does aquarium lighting change the color of a Green Moscow Guppy?
Lighting can significantly change how Green Moscow coloration appears to the viewer, especially because reflective green and blue-green tones respond differently to lighting angle and intensity. Lighting does not change the fish's underlying genetics, so photographs taken under different aquarium lights can make the same fish appear noticeably different.
Would Aquatic Arts recommend the Green Moscow Guppy?
The Green Moscow Guppy is well suited to aquarists looking for an active fancy guppy with extensive reflective coloration for a planted display or appropriately planned community aquarium. Aquarists should provide stable mineral-rich water, compatible tank mates, and a plan for managing fry if males and females are kept together.
