A healthy Fire-bellied Toad eat 2-3 times a week. You should offer not only aquatic food but also purchase some vitamins from market specially for toads and give him. I also suggest to discuss this with your vet.
My Fire-bellied Toad Hasn't Eaten For A Week,What Can I Do?
Try putting him in a 5 gallon tank for about a week. Or you should get another one because they are soicail creatures hope that helped
We put our fire bellied toad in bigger tank and now he seems to not want to eat. Is there something wrong or should we just watch him for a couple of days?
