Origin: Tank Bred. Assorted Moscow Guppies are produced in captivity, with many fish sourced from experienced local breeders who share our commitment to producing healthy, high quality aquarium fish. While the Moscow strain is a selectively bred ornamental variety that does not occur naturally in the wild, it traces its ancestry to the Wild Guppy (Poecilia reticulata), a species native to northern South America and several Caribbean islands.

Wild Guppies are naturally found in slow moving streams, creeks, ponds, canals, and other shallow freshwater habitats with abundant aquatic vegetation. These environments typically feature warm, mineral-rich water, submerged roots, leaf litter, and gentle water movement that provide shelter, feeding opportunities, and ideal conditions for reproduction.

Although Assorted Moscow Guppies have been selectively bred for their brilliant metallic coloration and flowing finnage, they retain the active, curious, and social behavior that has made guppies one of the world's most popular freshwater aquarium fish. Providing a well planted aquarium with open swimming areas, stable water parameters, and a varied diet allows these beautiful livebearers to display their natural behaviors while thriving in the home aquarium.

Aquascaping & Habitat

Creating an aquarium that reflects the natural behaviors of Assorted Moscow Guppies begins with balancing open swimming space and dense plant cover. These active livebearers spend much of their time exploring the upper and middle water column, so an aquarium with open areas for swimming and pockets of vegetation for security allows them to display their natural behavior while showcasing their brilliant metallic coloration.

Live plants such as Java Fern, Anubias, Cryptocoryne, Vallisneria, Water Sprite, and floating plants provide shelter for fry, encourage natural exploration, and help maintain excellent water quality. Floating plants are especially beneficial because they diffuse bright lighting and create a more comfortable environment while allowing guppies to display confidently.

Natural driftwood, smooth river stones, and subtle botanical accents create a beautiful freshwater aquascape without reducing valuable swimming space. While Moscow Guppies do not require heavy tannins, occasional additions of Catappa Leaves or other Aquatic Arts botanicals can support a healthy aquarium ecosystem by encouraging biofilm development and providing additional grazing opportunities for shrimp and other beneficial invertebrates.

Assorted Moscow Guppies thrive in peaceful planted community aquariums where every inhabitant serves a different role. Pairing them with Neocaridina Shrimp, Amano Shrimp, Nerite Snails, Corydoras, and Otocinclus creates a balanced ecosystem in which shrimp graze on biofilm, snails help clean hard surfaces, bottom dwellers forage along the substrate, and guppies provide constant movement and vibrant color throughout the aquarium.

Assorted Moscow Guppies are opportunistic omnivores that naturally feed on small aquatic insects, insect larvae, microcrustaceans, algae, biofilm, and plant matter. This varied diet provides the protein, vitamins, and minerals needed to support their active lifestyle, brilliant coloration, and continuous growth.

In the home aquarium, Assorted Moscow Guppies readily accept a wide variety of high quality prepared foods. A premium tropical flake or small community fish pellet should serve as the foundation of their diet, supplemented several times each week with frozen or live foods such as baby brine shrimp, daphnia, microworms, or bloodworms. A varied diet encourages stronger immune systems, improved coloration, and more natural feeding behavior.

Because guppies have small stomachs and fast metabolisms, they benefit from being fed small portions two to three times each day rather than one large meal. Feed only what they can consume within a few minutes to maintain excellent water quality and reduce unnecessary waste.

For hobbyists interested in breeding or maximizing coloration, increasing the variety of protein-rich live and frozen foods can significantly improve body condition, finnage development, and reproductive success. Occasional spirulina-based foods or vegetable-rich diets also provide additional nutrients that support long-term health and vibrant coloration.

Assorted Moscow Guppies are among the most peaceful and adaptable freshwater community fish available. Their active personalities, small adult size, and gentle temperament allow them to thrive alongside a wide variety of similarly peaceful species. They do best in aquariums with fish that share comparable water parameters and will not nip their flowing fins or outcompete them during feeding.

Recommended Fish Tank Mates

• Ember Tetra (Hyphessobrycon amandae) – Peaceful schooling fish that occupy the middle water column and complement the vibrant colors of Moscow Guppies without competing for territory.
• Harlequin Rasbora (Trigonostigma heteromorpha) – Calm, active schooling fish that thrive under similar water conditions and add beautiful contrast to planted community aquariums.
• Celestial Pearl Danio (Danio margaritatus) – A colorful nano species that enjoys densely planted aquariums and peacefully coexists with Moscow Guppies.
• Pygmy Corydoras (Corydoras pygmaeus) – Small bottom-dwelling catfish that help utilize the lower portions of the aquarium while remaining completely peaceful.
• Otocinclus (Otocinclus spp.) – Gentle algae-grazing catfish that thrive in mature planted aquariums and make excellent companions for Moscow Guppies.
• Kuhli Loach (Pangio kuhlii) – Peaceful nocturnal bottom dwellers that spend most of their time among plants and hardscape, adding activity to areas of the aquarium rarely occupied by guppies.
• Honey Gourami (Trichogaster chuna) – A peaceful centerpiece fish that shares similar water requirements and adds personality without intimidating or harassing guppies.
• Other Guppies (Poecilia reticulata) – Moscow Guppies can be mixed with other peaceful guppy varieties, although hobbyists interested in maintaining pure bloodlines should avoid crossbreeding different strains.

Fish to Use with Caution

Larger peaceful fish such as Angelfish (Pterophyllum scalare) or larger Gourami species may coexist successfully in spacious aquariums, but individual personalities vary. Closely monitor interactions, especially with long-finned male guppies, as occasional fin nipping or territorial behavior may occur.

Fish to Avoid

Avoid housing Assorted Moscow Guppies with aggressive cichlids, large predatory fish, or persistent fin nippers such as Tiger Barbs (Puntigrus tetrazona). These species may stress Moscow Guppies, damage their flowing fins, or outcompete them during feeding, resulting in poor health and diminished coloration.

Aquatic Arts Recommendation: Assorted Moscow Guppies truly shine in heavily planted community aquariums where they can be combined with peaceful schooling fish, bottom-dwelling catfish, freshwater shrimp, snails, and live plants. Building a diverse aquarium with species that naturally occupy different areas of the tank creates a healthy, balanced ecosystem while allowing every fish to display its natural behaviors.

Assorted Moscow Guppies are one of our favorite fish to keep alongside freshwater shrimp. Their peaceful temperament, small adult size, and active yet non-aggressive behavior make them excellent companions for many shrimp species. While adult shrimp are generally ignored, newly hatched shrimplets may occasionally be eaten. Heavily planted aquariums with dense mosses, floating plants, and natural hiding places greatly improve shrimplet survival.

• Neocaridina Shrimp (Neocaridina davidi) – An outstanding choice for planted community aquariums. Adult shrimp coexist peacefully with Moscow Guppies, while mosses and dense vegetation provide excellent refuge for newly hatched shrimplets.
• Amano Shrimp (Caridina multidentata) – One of our favorite pairings. Their larger adult size makes them ideal companions, and their exceptional algae-eating abilities help maintain a clean, balanced aquarium.
• Caridina Shrimp – Peaceful companions when maintained within compatible water parameters. Mature planted aquariums with abundant cover provide the best long-term success.
• Bamboo Shrimp (Atyopsis moluccensis) – Gentle filter feeders that occupy a completely different ecological niche. Moscow Guppies rarely interact with Bamboo Shrimp, making them an excellent addition to peaceful community aquariums.
• Vampire Shrimp (Atya gabonensis) – Large filter-feeding shrimp that coexist exceptionally well with Moscow Guppies. Providing moderate water flow and shaded hiding places allows Vampire Shrimp to feed naturally while guppies occupy the upper and middle water column.

Breeding Difficulty: Easy

Reproduction Type: Livebearer

Assorted Moscow Guppies are among the easiest freshwater fish to breed, making them an excellent choice for hobbyists interested in observing livebearing behavior or raising their own fish. Unlike egg-laying species, female guppies carry developing fry internally and give birth to fully formed, free-swimming young approximately every 28 to 30 days under ideal conditions.

For the best breeding success, maintain one male with two or three females. This ratio helps distribute the male's attention among multiple females, reducing stress while encouraging regular reproduction. Dense plant growth, floating plants, and fine-leaved species such as Java Moss provide valuable shelter for newborn fry and greatly improve their chances of survival in community aquariums.

A varied diet of high quality prepared foods supplemented with frozen and live foods helps condition breeding adults and supports healthy fry development. Excellent water quality, stable water parameters, and regular maintenance are far more important than attempting to manipulate water chemistry to encourage breeding.

Because Assorted Moscow Guppies are offered as an assorted color strain, offspring may display a wide range of colors, patterns, and finnage. Hobbyists interested in maintaining or improving specific Moscow characteristics should selectively breed only their best individuals and avoid mixing different guppy strains if preserving the distinctive traits of the Moscow line is the goal.

Aquatic Arts Tip: If your goal is to raise the greatest number of fry, provide dense mosses, floating plants, or a dedicated grow-out aquarium where young guppies can mature safely away from hungry adults. Well-fed adult guppies are less likely to prey on their own fry, but some losses should still be expected in community aquariums.
