Leopard gecko fat belly skinny tail?

[HaileyMD]

I had a question. I have 2 girl leopard geckos, Wyli who is 7 and Reggie who is 6. Reggie has always been nice and fat but rerecently I was cleaning their cage and I noticed her tail has gotten way skinnier and her belly way fat and round this happened in just a couple days. One of my geckos is having loose stool but I'm not sure which one because I haven't seen them poop but I think it's reg because Wyli acts and looks normal. Reggie has been soaking in her water a lot more and is pretty grouchy. Anytime I pick her up she grumbles at me. Theyre in a 10 gallon tank, carpet substrate, 2 caves to hide in, things to climb, eat about 30lg crickets twice I week, I use an infared light all the time and a white light during the day, I dont know the cage temps because my thermometer died and I need a new one but it's always been in the 80s. Last time I bought crocrickets Wyli was chowing down but Reggie didn't even stalk which isn't like her. She is turning white right now though and getting ready to shed.

Any ideas?

I'll post some pictures soon of what she used to look like, what she looks like now and her poop.

I would first and foremost remove her from your other gecko. My first guess would be parasites that are taking nutrition from her. There is a chance that she is using the fat supply in her tail to supplement for the nutrition the parasites are robbing her of from the crickets. The parasites will often cause stomach bloating (think newborn puppy or kitten). She will need to go to a vet for a work up right away, and they will want a fecal to check. I would also bring one from your other Leo, because if one has parasites the other most likely has it as well... just not as advanced yet. If it is parasites the good news is it is treatable. (Edit: Also, don't leave crickets in the tank more than an hour. They will eat the poop and up the parasite load just exasterbating the problem.)

However, this is just a guess and is not a substitute for veterinary attention. Put her in a seperate cage from your other Leo ASAP, and get her to a vet first thing! Most illnesses are treatable if caught early, but can be deadly if allowed to wait! Good luck!
