So I've come to the conclusion that I would like a wrasse for my tank for some prophylactic pest control. It's a 34g red sea tank with a pair of clowns, watchman, firefish, cave goby, and springeri damsel. I don't really want to go 6 line since they can be bullies, and a yellow corris gets a little big for the tank. I've heard a pink streaked wrasse may be a good option. I've also thought about a possum wrasse, but have heard the pink streaked may be better for pest control. Thoughts/suggestions/ideas?
