The Axolotl is a unique and fascinating cool water amphibian that is fully aquatic, and this is a very deluxe variant!


The Melanoid Axolotl (Ambystoma mexicanum) is a very unique salamander species that lives its entire life in the “larval” stage. It never becomes land-dwelling and is instead fully aquatic with external gills. This Mexican native is critically endangered in the wild, but is captive-bred by many aquarists and has been developed into many exceptional color morphs. It attains an impressive, but manageable size, and it is relatively easy in care provided that a few very important needs are met. This less common color variant is available as a natural GFP (Green Fluroescent Protein) type. The "glowing" coloration of GFP-type Axolotls can be seen under a blacklight or actinic blue light, but a blacklight should never be used because it will quickly damage the eyes of the Axolotl. Blue lights are safe for viewing the Axolotl.


Two of the most important aspects of Axolotl care are temperature and water flow. It is not a tropical animal, so it is critical that its aquarium is kept below 70° F (21° C), with 60-65° (15.5-18.3° C) being more ideal. While this temperature can often be achieved by keeping the tank at “room temperature” with no heater, it is important to consider any temperature increase that might be caused by aquarium equipment, particularly lighting. If the Axolotl is kept at too high of a temperature for more than a very brief period, it will typically stop eating and deteriorate rapidly, eventually resulting in death. It will not adapt to long-term high temperatures. It requires low water flow that is not concentrated into any direct-flow areas. A spray bar is very useful for this species. The Axolotl is not afraid to jump, so a tight-fitting lid is necessary to prevent it from escaping the aquarium.


The Axolotl is primarily nocturnal, but will often become active during daytime hours once established in an aquarium with plenty of smooth driftwood, plants, and other hiding places. Its skin is easily damaged, so decor with sharp edges should never be used. It does not require lighting at all, and it will be more outgoing with at least subdued lighting. Floating plants can help with diffusing light. Another crucial aspect of Axolotl housing is the substrate. It will often eat or try to eat anything that will fit in its mouth. No gravels should not be used for this reason, as they can cause impaction of the digestive tract of this species. A good rule of thumb is that the Axolotl will try to eat anything up to the size of its head. Very fine, aquarium-safe sand is a viable option for a more naturalistic-looking Axolotl aquascape, though many Axolotl keepers opt to use no substrate at all. While it does not require a particularly large aquarium for its adult size, the Axolotl does require very clean water and effective filtration with a regular water change regimen.


Due to its size and unique requirements, there are very few possible or appropriate tankmates for the Axolotl. Juveniles are notorious for biting off the limbs of other juveniles. While this species has the incredible ability to completely regenerate complete limbs, feet, and digits, there is still the possibility of infection from such attacks and juveniles should not be housed together. Adults of the same size can sometimes cohabitate, but it is not necessarily ideal for purposes other than breeding. If adults are to be kept together for purposes other than breeding, it must be in a gender-specific aquarium of all males or all females. Males will relentlessly pursue females for breeding, which will result in overbreeding and eventually death of the female in an aquarium setting. Females typically should no more than two spawns per year if they are breeding at all. The Axolotl is not a social species and does not benefit from being kept with its own kind. It will at least attempt to eat any animal that might fit in its mouth, so small tankmates will always be at risk. Other more active, boisterous, larger animals (especially fish) are often prone to pick at the Axolotl, especially at its feathery external gills. The naturally cool water Marimo Moss Balls are an ideal plant for the Axolotl aquarium. Other than hardy, low-light plants (such as Anubias, Java Fern, various mosses) that can possibly tolerate the lower temperature, the Axolotl is best kept in its own species tank.


With proper care, the Axolotl will typically live 10 years or more, and some specimens have been known to live more than twice than long in some instances. Like virtually all of its fellow amphibians, the Axolotl should not be handled unless absolutely necessary. If it must be removed from its aquarium in a rare instance, a fine mesh net is required so that the appendages, gills, and fragile skin of the Axolotl are not damaged.


Feeding is easy for the Axolotl. Live nightcrawlers (earthworms) and blackworms are excellent staples. Many specimens will also eat appropriately-sized meaty, frozen foods and cooked shrimp as well as dry foods formulated for salamanders and other amphibians. Mammal-based foods are generally too fatty and should not be offered unless absolutely necessary. The Axolotl eats relatively heavily and should be fed daily and, in the case of juveniles, generously. Spot-feeding near the mouth of the Axolotl with forceps or a feeding stick is often helpful and will reduce uneaten food. Uneaten food should be removed and replaced daily.

This colorful tetra is a true aquarium hobby classic!

These little tetras are one of the more beautifully colored fish available in the freshwater aquarium hobby!  They have a silver body and feature a shimmering red/pink stripe throughout the middle of their body.  Their eye-catching coloration has made them one of the most popular fish for freshwater aquariums today.  They are great for beginners and experts alike, and they thrive in any well-established aquarium that meets their recommended water parameters.  These fish stay small, growing no larger than one to two inches, which makes them an excellent choice for small-sized tanks!

Glowlight Tetras are very peaceful and make great additions to community aquariums.  However, they should only be kept in tanks with other non-aggressive fish that are similar in size.  They are a schooling fish, and their schools create a magnificent display of colors in motion that has to be seen to be believed!  These fish do best in densely planted aquariums with plenty of hiding places.  This can be achieved with rocks and caves, driftwood, and live plants (good ones include mosses or tall plants that will reach the middle level of the aquarium, such as green cabomba, moneywort, java ferns, etc.).  Since they are a schooling fish, they can really only thrive in groups, which is why we sell them in groups of 6 and 12.

Glowlight Tetras spend most of their time within the middle and top levels of the aquarium.  These fish are not recommended for new tanks, as they may have problems in tanks that are not well-cycled.  It is important to acclimate Glowlight Tetras to a new tank slowly, because they can be sensitive to changes in water parameters.  They are known to be difficult to breed in captivity; the water conditions must be perfect for them to spawn.  Interestingly, the bright colors on these fish tend to become dimmer at night.  This is normal and does not indicate sickness or weakness in the tetras.

Shipping Schedule for this service

UPS 1 Day: Monday through Thursday

Current Handling Time:

1-9 business days

Here at Aquatic Arts, we consider the welfare of the live animals we are shipping to be of the foremost importance. This process is much more involved than simply creating a shipping label and affixing it to a box. Depending on the order, it takes from 4 to 7 people to complete this process properly. We check the weather conditions here where they fly out of the Indianapolis UPS facility and the destination for each shipment. We start early each morning and go through a multi-step process to have the day's shipments prepared in time for the UPS pickup. The volume of orders in our system also affects the processing time. Therefore our stated handling time is 1-9 business days. 

Shipping Rate

Pricing is by size of package needed to fill entire order and distance it must travel. It will be calculated at checkout.



Q: What are the ideal tank mates for Glowlight Tetras?
A: Glowlight Tetras do best with other small, peaceful fish. Ideal tank mates include Neon Tetras, Harlequin Rasboras, Corydoras Catfish, and small livebearers like Guppies or Mollies.

Q: How often should I feed Glowlight Tetras?
A: Glowlight Tetras should be fed 1-2 times a day. Provide only as much food as they can consume in 2-3 minutes to avoid overfeeding and water quality issues.

Q: What should I do if my Glowlight Tetras are not schooling?
A: Ensure you have at least 6-12 Glowlight Tetras, as they are schooling fish and feel more secure in larger groups. Also, check if there are any stressors in the tank such as aggressive tank mates or poor water quality.

Q: Can Glowlight Tetras live with shrimps and snails?
A: Yes, Glowlight Tetras are generally safe with non-aggressive invertebrates like shrimps and snails. They add a nice dynamic to the aquarium and help with cleaning.

Q: How can I tell the difference between male and female Glowlight Tetras?
A: Males are usually slimmer and may have more intense coloring, especially during breeding times. Females tend to be rounder and slightly larger, particularly when carrying eggs.

Q: What signs of illness should I watch for in Glowlight Tetras?
A: Watch for changes in color, fin rot, spots, or unusual swimming behavior. Common illnesses include ich, fin rot, and swim bladder issues. Quarantine affected fish and treat the tank if necessary.

Q: What lighting conditions do Glowlight Tetras prefer?
A: Glowlight Tetras thrive in subdued lighting conditions, which mimic their natural habitat. Moderate lighting with plenty of plants for shade creates an ideal environment for them.
