I have my crosshatches in a 210 with clowns, mandarin, and an anthia and lineatus wrasse. They have never even once shown any interest in bothing any of these comparitively smaller fish (my male clown is only about 1" or 1.5"). However, my male devoured eight chromis in about 3 days. I have 4 cleaner shrimp, and few peppermints, and starfish- no problems whatsoever. Actually, the cleaners swarm the male at night.
