identification of a nudibranch --- reef safe ???

[Skimmer Juice]

looks like a zoanthid eating nudi. Check all your zoas , make sure there is no eggs I had them and they can wipe out colony's fairly quick . thats why its important to dip all new corals. I guess the coral rx dip does not kill them it will just stun them so go over the colony/frags with a magnifying glass to make sure you knock the eggs/nudis off. there is also a post reefwars made on reefcentral I believe that covers this
