I had Dovahkiin (how did I just now notice that I've been mispelling his hame? I'm such a bad mommy! Q.Q) in a half gallon tank like that. Be careful about the "backing" that they put in it. I woke up one morning and the paper had separated and part of it rolled ONTO him!!!! I immediately flew out of bed and took it out. Also, I kept the entire area around the lifted spot covered in gravel and put a small patch of "grass" in the middle. He loved cuddling in the middle area. Hope that helps. :) Sorry if my typo misled you!
