Hello! I work in the aquatics department of a pet store that I've been employed at for a bit over a year now. I also have two young Axxie's that I got in late June. Right now they are perfectly fine in their 15 gallon tank, but I'm planning on moving them to a 30 or 40 long so they can grow and be happier.
All the axolotls we sell in our store live with other fish, be it goldfish, plecos, or angel fish. Usually we've had no problem housing Axolotl's with bigger fish (fish they can't fit in their mouth) but you have to watch carefully and make sure none of the fish mistake the Axolotl's gills for food.
I feed my two (Aristotle and Toothless) frozen bloodworms, but every once in a while I throw in some ghost shrimp as well.
Feel free to ask me any questions you have about these cuties!
