I got them as a gift from my brother, who had picked them both out at Petsmart. Probably not the best place to get them I guess, but outside of paying a lot of money to ship one, it's the only place that carries frogs around me.

I had noticed this frog would drag its nose along the glass and kind of poke it along the corners, I guess I didn't even think about it being an issue, because it mainly did so along the doors where the tank opened after it learned that was the way to get out of the cage with feeding time. I do have two sides of the tank covered, but never thought about covering a small strip around the bottom, thanks for that tip.
