Tired of you? No
I think you need to bump your temps a little on the warm side and a lot on the cool side. Cool side ought to be around 82 or so.
Also, have you tried a rat?

I don't know what the environment is, but it sounds like this little guy needs to be in a very small environment; like a 16qt tub.
What do you think?
