I already have the Cleaner Wrasse I know I shouls of researched it first, I got him for free I had some LFS credit and saw two there and talked to the guy I know at my LFS and he told me if they don't find parasites he'll eat brine and mysis shrimp stuff like that. He eats anything I put in the tank but I don't think he's found any parasites, He also has stopped looking around and just looks for food for me to feed him. I've had him since last saturday and i'm hoping he stays how he is now which is healthy.
