Blenny nipping at tangs and clowns...

[dc4]

Anyone ever have their blenny nip at other fish when they swim by? I bought a bi-color blenny a few days ago and it decided to set up shop in a hole right under the rock where the bta's that my female clown host in are. I read that they are peaceful before I bought it but its going after anything that swims by even though its the smallest fish in the tank! My new tomini tang has a new rip in the tail and its either the female clown who is very protective of the bta's or the new blenny. I have tried getting the blenny to relocate to the bottom where a niece piece of calcified barnicle with 4 holes are but it shoots back into the hole in the rock anytime I get near it.
