Ok so lately I tried the 12qt Sterlite setup which I found pretty hard to believe that it was beneficial but I finally tried it. I had him in a 35qt which is the same size as a 21qt, but just higher... I think. Anyway here is how it looks, so I need a few people to say that it's fine, because I think it's cramped up. I am debating on taking one of the hides out since he is in a pretty dark area under my other tank, so let me know what you guys think.

Here is the tub:



Hygrometer: (I need help getting this down, or is it fine?)



Thermometer: (it's blurry of hot side (left hide))



And my "Lemon" pastel which was yellow when I got him, but now looks like this...:
