I have two females almost 2 years old now. One of them seems depressed. she has a bloated belly a bit. and a thinner tail. she wont eat and kinda just sleeps all the time. She used to be really keen and active. Im not sure whats wrong. she is in a 20 gallon 2x1x1 tank with her sister. the space is great. she has a moist hide box and three hides in there. repti carpet cleaned once a week. she will and was only eating dusted waxworms. is this the problem? there is no way she is impacted there is nothing in there to impact her.??????
