I'm trying to do research to get to the bottom of this question. A lot of care sheets say (White's in specific) Tree frogs are not great swimmers. Do not provide a bowl of water that is too deep or the frog will drown. However, when searching various forums, I've come across the fact that hardly anyone has a frog who "drowns"... its usually found in its bowl of water and had died from other causes.

Let's try to shed some light on this myth.
