I had a regular fox head of face rabbit fish... maybe it was horse head rabbit... yellow with a snout definitely a rabbit fish. Did real good until he developed a taste for zoas. Bent over backwards catching him, traumatized the entire tank trying to get him. Finally cornered him and was able to reach in and gently lift him out. Real skittish fish. I learned later about the tines on its back.

Save for the fact that they tend to have a negative reputation I would recommend the cow fish as mine eats calupra both grape and razor. I think all he has to do is someone else eating it and he's good to go... much easier to catch. I routinely catch mine in a cup while feeding. Just dip the cup with some food in it and when he swims in gently pull it out of the water. He will continue to eat until there's no more and then actaully looks a little surprised that he's in a cup. But he does it again just a few moments later.
