So...my RBTA split. Yesterday I found the newbie in the back of the tank and really didn't think much about it. Today, I found out why. He has attached himself to the cuc. Should I be concerned? This is a Caribbean cuc I have had for years. I did reach in and try to separate, but no go there and did not want to hurt either of them. Should I just hope that BTA will attach to a rock at some point?
