They do a good job of eating coral pests.Just about to put an order in for a Melanurus wrasse. They just came in today so once they are ready I will be ordering. I have been bugging the manager of Canadacorals for weeks to place me an order, can't wait! I have many flatworms still in the tank even after using Flatworm exit, do you guys have a Melanurus wrasse that eats flatworms?
I visited a reef store about 4 hours away last year and they had a Melanurus, I stood there watching him for at least a half hour. I wanted one ever since.
