So I just bought a 320 gallon tank with a 75 gallon sump and I want a few tangs, I'm going to get a purple, yellow, blue hippo, maybe sailfin but I'd like to get both powders but I see people that say it's not possible but all the one's I'm going to get will be juveniles and I'm gonna try to add them at the same time, is it possible to have both or should I just pick one?
