Please help, I have only had my 2 American green tree frogs for 3 weeks and 2 days ago I noticed that one of them has a weird growth on his belly, I have picked him up and tried to look to see what it is and its very soft and looks like its coming out of his tummy, Im really concerned he has cut himself open and his guts are hanging out. I have checked the tank over and found a sharp edge on one of the plastic plants, which I have now filed down so its smooth, I have tried feeding him by hand but he is not interested and is a lot smaller than the other frog. I don't know what to do for the best, please help? thanks in advance Nikki Ryland
