Kris, How long have you had the nems in the tank? I'm no expert on nems, but the carpets don't look any bigger than the tangs. Unless they are baby carpets, they can't be that happy. Even smaller carpets spread out, and take up a fair amount of room. Again, I'm no expert, but I've heard people talking about different species of nems "waging war". I've also heard a lot of horror stories where peoples purple tangs and other fis become nem food. I say I've heard, because my nems are in more aof a species tank, Haddon w/ saddle clowns. Haddon with clarkii, RBTA w/ maroon. That is what nems do, eat other fish that are'nt clowns. I could be wrong (love to be in this case actually). But I'd like to see update pictures in 1 month, 3 months, 6 and 12.
