I have 2 frogs i got them today the lady at the pet store said they never leave water and so did online. I put a little bit of the tank elevated with gravel so the frogs could go up there. they love being out of the water and on the gravel sometimes and also try to jump out of the tank with is 16 in tall and the frog can jump about a centimeter. Is this okay for them to be out of water. also one seems a little sluggish or depressed is this because of the recent change from his home. please let me know?????
