As the title states, I'm thinking of added one to my 125 reef. Reef currently houses a clown and a mimic tang, along with the basic cleanup crew. I'd like the wrasse for two reasons, first, I think they're quite neat fish and it'll add great variety. Second, there is a small chance he'll help me clean up flatworms. (I fully understand he might not want to) I do have the top of the tank screened to prevent jumping. Is there any reason why I shouldn't get one?
