I have two Axolotls, Marshall (who gives me my screen name) and Maynard.

A 10 would be okay for a juvenile, but you really wouldn't want to keep one in it long term. They get to be about 10-12 inches long, so picture a ruler in your tank. They also like to swim, and they can't really do that as adults in a ten.

If you do decide to get a juvenile anyways, know that sand can be devastating to filters. I personally use large river rocks, and I have been fine. You just have to move them around to clean it. Definitely no gravel.

I have live plants, BUT they do uproot them every time I turn around. Higher end silk plants would be your best bet, because I know mine like to cuddle into them, and some of the plastics can be pointy and sharp.

Whatever filter you decide on should minimally affect water flow in your tank. Axolotls really don't like moving water.

Also! They should NEVER be above 70 degrees, and your goal should be 68 degrees Fahrenheit.

They are really wonderful pets. Feed them earthworms, store bought Trout Worms seem to be the best. Feed them at night. Leave the light off most of the day. Also, they seem to like to interact, so spend a little time in front of the tank everyday. Please PM me with any additional questions. I love talking about Axolotls!
