Keep this in mind: Although they may seem easy to keep, axolotls are not low-maintenance creature. I mean, these salamander is almost cartoonish. But you need to know that they’re finicky when it comes to their habitat.
Most people makes the rookie error of keeping them as if they were typical tropical fish. Axolotls originate from Mexico‘s cold water, so heat kills them. Second, axolotls are bottom-dwellers, meaning they’ll consume whatever’s available on the bottom of your tank.
Wrong temperature plus sharp objects = a sick axie or a very short life span. General aquarium guide don’t apply. Ignore them.
Stressing the animal by keeping it in warmer then ideal water will shorten its lifespan and cause disease. Most tanks is simply set up wrongly. To be clear, the tank has to be thought of as special eco-system with special needs for water chemistry and environment.
The physical layout and water chemistry has to meet the animal’s biological requirements. Following standard goldfish/betta advice won’t work for axolotls. Focus on two primary aspect: substrate safety and temperature control.
If you get these wrong, everything else are irrelevant. One of the main factor for maintaining healthy axolotl is temperature. Water should be maintain at 60-64 degrees Fahrenheit.
Essential Steps for Axolotl Tank Setup
Temperature Control and Cooling Solutions
Above 68 degrees, the animal starts to became stressed out; above 72, it’s dangerous. Because most houses is too warm for that spectrum, your tank water will increase in temperature naturaly. In the summer months, an open top tank will not adequately cool the water.
You must employ an active means of cooling. The easiest way is with a aquarium chiller, which cools water as it pass through a cooling coil. This maintain the water at a constant temperature.
Chillers can be expensive and noisy, which is a valid concern for bedroom setups. Plus they may not works well in your bedroom. If you have a small tank, consider using a Peltier cooling pad instead.
The tank sit on top of the pad, and it sucks up heat from the bottom. It’s not as effective than a chiller but will do the job. Alternatively, you can have another container of cold, dechlorinated water sitting in fridge.
Use this water to change out some of the water and cool down the tank. That cools it down temporarilly. It won’t solve the bigger issue of how hot the room is.
Safe Substrate Choices for Axolotls
Substrate is important for the axie’s physical well-being. They will ingest anything that resembles food. If you use small gravel, they will inhale it and end up with blockages in their digestive tract which usually prove to be fatal.
If you have large river rock, beware of sharp edges. A bare bottom tank with a silicone mat is the safest. It may look boring, but it is the safest option.
With a simple floor cleaning nothing will get left in hard to reach places. A safe substitute to no substrate are smooth, large (over 2″) river rocks. They should of be too big for your axolotls to fit in their mouths.
Fine sand is okay as long as you clean it frequently. Over time, sand compacts and traps waste which create toxic pockets. While many people prefer the look of sand, it’s a bit more work.
It’s a matter of aesthetics vs. Workload. Make sure the plants (if there are any) is either fake/plastic or are anchored down so an axolotl cannot dig them up. Live plants will leech nitrates into the water, and nitrate levels is not good for axolotls.
Plants and Tank Decoration Safety
If your tank has live plant, place them in a mesh bag that allows water to pass through. It should be a cool, clean environment. Avoid anything with tiny holes where gills could gets trapped.
Gills are important for breathing, and damage may lead to infections. The tank setup have nothing to do with decoration. It’s an engineering feat.
It’s creating a safe environment for a fragile creature. That equipment appear industrial but is there for a reason. The chiller regulate temperature; the empty substrate guards the belly.
After that you can add what you want. Function always comes before everything else. The healthy animal makes it all worthwild.
