So it looks like this guy is not a bullfrog. I think he is a Northern Green Frog? He appears to have ridges.

Anyway, he is still not eating. I'm going to try small earthworms. I've let him be in the tank except for gently washing him over with water every couple hours to keep his skin moist. Today I did a pedialyte soak, from which he perked up a bit, but currently he's laying with his face resting on a tuft of moss at the base of the plant in his nursing tank. While I was transferring him from the pedialyte soak to his tank, I applied bacitracin to his leg with a Q tip.

He seems to be getting darker in color? Darker green. I don't think he looks so hot today. I was really hoping I could help him out. Poor guy
