I have an axolotl named brucey.. Its actually a she but we didnt realize this until after we named her. for nearly 2 weeks she has not eaten anything. she is usually a good eater. she is really skinny and her colour is changing to darker. She is still active swims round the tank etc. i am really worried and want to fix her.. does any one know what may be her problem, i recently looked after my sisters male axolotl but he has gone back to my sisters house, they were in the same tank, could she be depressed cos of the seperation?
