Thanks for all the advice! I haven't had a chance to reply sooner. I did sign up for the forums, but haven't posted yet. I'm getting all my questions answered by reading previous posts. It's a VERY cool site and a VERY informative forum!

Grippo is very cage territorial. We are looking or a nice big affordable tank for them. The cage we have for them now is just that. A small cage. I have a big tub I put them in for a few hours a day and play with them while thy are in the tub. The cage is far too small for the both of them. So until we can get a nice big tank for them we are giving them plenty of outside the cage time. The more time outside of their cage the less they fight when they are in their cage.

Another thing we've found is that we will need 2 wheels when we get the bigger cage. Why they gotta be on the wheel at the exact same time is beyond me!lol The cage their in now isn't big enough for 2 wheels so we gotta wait!
