I agree with Carlos in that they are most likely acclimating. Even though one was established, there's a new guy in town and that causes stress. Imagine how you would feel if you worked in a little cubicle and a stranger was thrown in there to work with you as well. Think your stress level would go up a bit? Lol

As far as the light goes, it shouldn't be affecting the frogs whatsoever.

Thanks for the answer! I know exactly how I would feel LOL!
