I've seen Maroon Clowns make just about anything a host, such as Frogspawn, Xenia, Sand, Toadstools, Goniaporas (they killed it), and Anemones to name a few. Keep in mind that they are also One of The Most Aggressive Clowns. Personally I would go with the Ocellaris Clown. They are one of the least aggressive clowns (toward other fish). They are also one of the most recognizable fish in the world. It might have something to do with that Nemo movie.
