I just watched a video of Barry Neigut's presentation at last years
IMAC. In it he talks about two types of wrasse that can be used to control clam preditors. One was the Six-Line Wrasse, the other one was another wrasse but I couldn't undertand what he said because of the audio quality. He said that they actively search for the Pyrams snails. It sounded like horse wrasse. Anyone know what it was?
