the killer hippo tang

[knorsk]

So I have had a FOWLR set up for about 3 months or more now that is understocked as it only has a citron goby, a mated pair of ocellaris clownfish, and a koran angelfish juvenile. So I decided to get a peaceful (or at least what i've been told about them) regal tang. All the fish have been in great health and have had no nips from territorial disputes or anything. However, after rearranging the rockwork and adding a hippo tang a week later I have noticed that the female ocellaris clown has a nip on it's top fin and the citron goby has a nip on it's tail fin. I'm just wondering if the added fish has ****ed off the angelfish or what. Also all the fish are within an inch of each others size. The hippo is the largest followed by the female clown then the juvenile angel, male clown and smallest the citron goby. Any ideas as to what caused the nipping or who is the culprit?
thanks

I had 2 Heniocus that always swam together. I put in a BlueTang and he tried to pair up with one and would run the other off. He always kept them seperated. He also kept bitting at the fin on the one , trying to run it off. I left him in for 2 months waiting to see If he would adapt. One day I came home and he had bitten almost the entire fin off. I was so mad, I snatched him out right away and stuck him in a QT tank without any acclimation. He got traded in the next day. I'll never buy another.

I have a blue hippo tang thats about 8 inches and he is constantly picking up blue legged hermit crabs and carrying them around the tank trying to eat them. As far as other fish he's real good tho... No problems. And i have 13 tangs in my tank

the regal or pacific blue tang is the only tang that is borne a carnivour. As they become adults they lose the task for meat and prefer salads(become herbevoirs)
I have 4 tangs--the blue being the largest---but it is also the most docile. However I have seem him use his size to muscle in on the other fish if I put a stick of nori in the tank
