I have 3 Retics, and the one female has stopped eating. She won't take anything to eat and her hip bones are showing. Thought it might be that it was 2 weeks since I last gave them blackworms but yesterday I feed them blackworms and it looked like she was eating them but this morning she looks thinner and I tried to feed her some more but now she not interested at all. Any sugestions what to do with her.
