I have a 55g and am wanting a wrasse. But I would like your opinions concerning the pros/cons about adding a yellow coris wrasse or a sixline wrasse. My stock list already is one percula, orange tail damsel, orchid dotty, and a flame angel. I know the sixline is aggressive but I think my stock list is aggressive enough to handle a sixline. Also, will a yellow coris eat the worms and other unwanted critters like a sixline?
