Hello! I have a 10-gallon tank I am setting up that is ready for fish. I am putting a molly miller blenny in there because he has been a bad clam nipper, so he is going in his own house. Are there any other fish I can add that will peacefully coexist? I am hesitant of clowns as I don't want them to mark the whole tank as their territory, which I assume they most likely will, and harass my blenny. Maybe a shrimp/goby combo or a plethora of inverts like sexy shrimp? Thanks for the suggestions.
