--On my short list for favorite fish, I have had one. I had it for a couple years. I can't remember the details, but I know there are vriations of the fish based on where you get them.....something about purple or coloration or something. Anyway, I think there was a specific HT that should be avoided because they were most likely collected with cyanide--not sure if it was the Phillipine variety?
But yeah, they will wipe out shrimp, crabs, and snails. I would definitly do one in a larger reef tank. Great centerpiece fish IMHO
