Hi I have had Lrrr since November 2009 and he's been just the easiest captive. However, for about the last week he's been sleeping in some really strange positions that vary from your standard cryptic tree frog sleeping pose. He sleeps with his legs bent away from his body and looking as if he's inhaling as much as he can. His sides look like they're compressed. He's eating normally and isn't acting lethargic and the tank conditions seem to be within appropriate parameters.

Any suggestions?
