Hi, I hope I'm doing this correctly, I've never posted before.

Anyways, I need help /advice. I found one of my frogs out of the water. I don't know how long he was out, but I pushed him back in. He swam feverishly trying to stay at bottom of tank, but he keeps floating back up. He can't stay under water. We are on day 2, and he now just floats around. Is death inevitable? Is there anything I can do to save him?
