I have 2 Barking Tree Frogs.
One is a plump "normal" looking frog, with his normal colors.
The other, is okay looking, (not too fat), but is very bright green, but, has been just hanging out at the water bowl for the past 4 days. Should I be concerned? He or she doesn't look sick, just sits there content. Except I have to move him manually when I change the water, he doesn't get annoyed at all. Just hops back to the water by the end of the day!
