So right now,I have 2 eels and a coral beauty... I am going to pick up 2 yellow stripe maroon clowns, but I really want to stock up on some tangs... Is 3 too much in the 135... I have my heart set on a clown tang... Any negatives on this fish... Also, everything I read about the tangs I wanna keep, tell me they are all very territorial, such as a Sohal, Vlamingi, and Achielles... Can I keep more than one clown tang, or will they continue to fight it out? I might just pick up a blonde naso and a clown... Also any thoughts on running a UV steralizer off and on to help with parasites... I know quite a few reefist who use them intermitely to fight off disease...
