Alright here's another question, at my LFS, they have 3 SFE's, 2 togother with smaller fish, and 1 SFE with some tangs and angels. The solitary snowflake is always out swimming the holding tank back and forth end to end. The 2 together just hanging together in some PVC. They look about the same color/size wise, which would be the one to get? I would think an active eel would be cool, but would he wear himself to death?
