Again, not to rain on your parade, but about that fish (not the anenome). The water at Catalina Island is coooooold--as I'm sure you know living in LA.
Soooo, these are NOT fish that should be added to standard tropical reef tanks. We can predict with high confidence that your goby will appear healthy but will live a significantly shortened life---I think I've read they make it maybe a year in warm tanks. He needs to be in a cool tank of 70-72 degrees. In LA, I bet you could find someone with an appropriate tank for him, OR could get him to a LFS that carries these gobies!
