I can't believe how well mt RTS get along with his tank mates The corys even share the same cave with him. I must of lucked out and got a docile one.

I'm glad to hear that things are going well. I had the same experience with my Rainbow Shark when he was a juvenile. His best buddy was also a Cory Cat. The aggression/chasing issues began as the shark began to mature. I never see him/her bother my bottom dwellers, Cory Cats and Pleco but he gives my Silver Dollars a run for their $ (no pun intended).
I just don't want you to get your hopes up that things are always going to remain as calm as they are now. Maybe things will continue go go smoothly but I recommend a back up plan just in case things do change
