I am currently deciding how I would like to complete the fish stocking for my RS Reefer 300XL (~3'x2'x2'). I currently have a pair of yellow coris wrasse's (one is a juvenile female, and the larger one is clearly dominant and transitioning to male). I also have 3 azure damsels that bicker some amongst themselves, but are completely submissive to both wrasse's. I would like to add 2-3 smaller fish. With an established pair of yellow coris wrasse, are any other wrasse additions likely to cause trouble? Maybe a pair of bartlett's anthias? A pair of black cap basslet's? I like to keep my fish in pairs/groups whenever possible. Suggestions?
