Okay I'm STILL trying to figure out what type of clowns to get for my tank... 37g, reef, and I'm deciding between clarkii or sebae. NO I'm not going to get percula or occelaris or black and white perc/occ. Everybody has them. I don't want them. I want something different. So... apart from appearance, what are the main differences in those two clowns. There's not much info on sebae clowns. I know they're rarer, but my lfs gets them regularly. They sell them seperate from clarkiis. So I'm pretty sure they're actually sebae clowns.
