spawning clowns

Tonight I noticed that our Koren Angel was being picked on by our male maroon and yellow tang, in which neither are normally aggressive. All while the female maroon was acting normal... Aggressive, but not overly. I worried that they were severely hurting the angel so I turned out the lights...
