Oops sorry...that tank would be perfect for fire belly toads. Although they can climb they don't usually so you WOULD want more floor space. I would go for the one you mentioned. I've got two Exo Terra's and I love them. Now they do make a 36 inch long but it does start to get pricey. A good thing about their tanks is that the lids lock into place.The firebellies wont utilize the vertical space hardly ever but when they first get into the tank they will test every corner for an escape route or a weak point. And they can be relentless if they find one. You look at them and you would think, how could they climb the glass they can barely jump but you wait and see they they'll do the Jackie Chan up the corners of the tank in no time flat.
