I have one of the giant ones....I have had it for almost 2 years and it has never split, I also feed it a few times a week. It is about 8-9 inches across now. When I first got it i was only 2 inches.....Gary M has some of the bigger ones too, they are relatively new to the hobby, just coming in in the last 1-2 years. Mine has never moved from the place I put it when I first acclimated it. Clowns do not seem interested in them either....I have pics if you want to see them.
Yours is real pretty Donavon.....
