Our of my three, one of them is quite chubbeh. I think it's cute but I've read multiple times they shouldn't get that big. I feed mine every other day, 3 crickets each. The other two are a lot more active (swimming wise), I guess that's why, but Fatty (aka Azazel) just sits there, eats and occasionally tries to nom on one of the other two (boredom, guess that's what it'll do to you.) I bought a lot of stuff to put in the 'dry' side of their tank (I have a half/half one set up) and they rarely go over there. They swim, hang out in the water plants, and sit on the dock all day.
