It was a juvenile six-line and a huge cleaner shrimp. The shrimp was starting to get aggressive with the smaller fish in the tank and would stalk up on them whenever he saw one near. The wrasse happened to check out a hole in a rock the shrimp was perched on and was still inside when the shrimp darted up and jabbed its claw inside. The wrasse came out injured and was immediatly snatched up by the shrimp. I didn't even have time to open the hood before it was all over. I decided I had had enough with unpredictable inverts and traded in my cleaner shrimp, 2 camels, brittle star and red emerald crab the following weekend.

My six-line was never aggressive with anything in the tank. The one I had for about a year got to be pretty big (not as big as CanadianMan's though) but never bothered anything.
