Sounds good to me Stu. In my 30 cube I have a misbar percula, a fridmani dottyback, a bue neon goby, yasha haze/tiger pistol pair and a recently added a 5 line wrasse. The mystery wrasse gets to be about the same size as the 5 line that I just bought and if it's behavior is anything like the 5 line's, it'll be cruising all around the tank. I mean...constantly cruising around. So far, it's left my skunk cleaner alone.
