I've had my albino Axolotl for about a year now. I think she is about six. She is growing a lump on her belly that seems to be getting larger. It's the same colour as her skin and it doesn't look inflamed or bother her in any way, but I wondered if Axolotls get lumps as they get older? I clean the tank regularly and she is in a very large tank, but I want to make sure she's not getting sick. She eats fine and is as active as she's ever been (which isn't much. She seems to swim only when I'm not watching her, then she sinks to the bottom like I caught her in something bad. ) We have an exotic pet vet not too far from here, but I'd rather not stress her if she is fine. I can try to include a picture if you need one, but as she mainly sits on the bottom of the tank, it's hard to see it. (I don't think I can attach a picture until I've been on the forum for a while, but I can put it somewhere to view)
