Hi,

I have (what I believe to be) four green American tree frogs that were given to me by a friend. They are still babies and I want to make sure that I'm caring for them correctly. I've had them for about two weeks and have been feeding them dead fruit flies that I capture from my worm bins. I feed them using a toothpick. A couple days ago I bought a reptile calcium powder and have dusted the fruit flies twice. I know they probably need a multivitamin as well. What would you recommend and how often for babies? Also, one of them seems to be sick. He is much smaller than the others and stays on the ground instead of at the top of the tank. He also doesn't want to eat, is sluggish and has turned brown. I've tried giving him a pedialyte bath, but he hops out of it. Instead I poured pedialyte on him directly a few times a day and the next day he did seem better and even ate three fruit flies (with calcium powder). Today he only ate one and he seems sluggish again. Any suggestions? Could it be calcium absorption? Does the tank need a UVA/UVB light for them to be healthiest? I took him out to the sun for 15 minutes yesterday (with shade optional of course) and a couple of them did sun bathe. Could this be the problem? Additionally, one of the other tree frogs has turned brown, but he seems to be in good health otherwise. Is there a reason that they turn brown?

Thank You!
