maroons are some of the most agressive clowns known to fish. It will be hard to pair a maroon with another maroon if they havn't been together long term, much less put percs in there. I have two pairs in my 90 bowfront but they are clarki and falsepercs, False percs stay on the top right side of my reef in a Ritteri Anemone, and the clarki's stay in a sebae on the bottom left side of my reef. There are big issues with territory but nothing to bad. I deffinately wouldn't try maroons though. My case is rare.
