Sorry about the anthias, it was a real beauty. At least you have the leopard wrasse. We are all jealous of that one! Those hawkfish are some funny dudes! Saw a flame one at petco today. The falco's are pretty cool too. You could always get a dottyback.
SD, some blennies can be butt heads to say the least. IME, the Ecsenius family seems to be the most common ones to nip at whatever they want. Not sure what Brian had, but if I had to guess, it was probably a Ecsenius blenny. The fang blennies (Meiacanthus) usually don't bother stuff like that, but there are specific species of them that can put a hurting on other fish like that one that mimics cleaner wrasses. There are ALOT of different blennies out there.
