Thanks everybody.

The thing is, I actually rescued the small one from a friend who's son won it but did not have the means to take care of it. He has been in 2 months and has been fine, but the other day I saw that a part of Ikes tail was missing.

He doesn't even seem phased by it. Do you guys think this will progress into a debilitating or fatal attack on the little guy, I would never want that. I just don't know what I could to with him. I live in the city and in a 1 bedroom apartment and can't release him or get another tank for him. What are your opinions. Thanks.
