I will be moving my fire bellies from a 10 gallon to a 20 gallon long tank soon, and then, well, I'll just have a tank sitting around. I don't want fish. I'm also looking for something that's pretty easy to feed--either canned food readily available from the pet store, or crickets. Also, I'm looking for something that's pretty active. It'll be a class pet, and while I will never allow the kids to handle the animal, I do want it to be something they enjoy looking at. Any suggestions?
