I will need a bit more information so that I may best answer your question.
Could you please give me more information about husbandry such as tank size, heat and light source, hours of light, plants, food source, other frogs, fish etc. Any change in the enviroment etc?
Are you keeping the tank colder to stimulate hibernation? Please list any thing at all no matter how trivial it may seem.
He bury's himself in coconut fiber, he is moist, he does not have a water dish, becuase he never used one. His hours of light are daytime hours. He has a heat source located on one end of the tank (40 breeder) 75 watt night lamp. I have never kept the tank colder to stimulate hibernation...
The last time he tried to eat, he took in a little bit of coconut fiber, then immediatly lost interest. No other plants in the tank. He eats small rats, or large mice. He will not eat frozen mice, or fish.
I moved to half way across the country a month ago, but he did not eat the month leading up to the move either.
I am running the same setup with a smaller Pixie frog, and he/she is doing fine in it, eating the same diet.
The house temp is always betwwen 68 and 77, shoud I just kill the heat source... also how long can they go with out food. How long should his hibernation period be, and should I do this with the pixie frog as well?
Hello, Sorry about the delay in getting back to your question. I was at a Veterinary Conference.
Unfortunately, after searching my information sources I have been unable to come up with a definative answer for the cause for your pac man frog's anorexia.
There are many reasons for Pac man frogs (South American Ornate Horned Frog), to stop eating for a short period of time. These include: temperatures too cold or too hot, kidney disease, constipation or colon impaction, chemical abnormalities, vitamin and mineral deficiencies (most commonly Calcium and Vit. D-deficiency causing Metabolic bone disease), too much dietary fat (feeding a mice only diet instead of insects) cancers, parasites, toxins and more.
I think it best to take him to a vet who is versed in amphibians and exotics. You may also be able to get more help from your local Aquarium or zoo, or pet store.
The West New York Herpetological Society as well as other web sites do have a lot of good information also.
