Any suggestions of a good wrasse or other fish that would get along with my carpenters that would be good for removing nudibranchs, I had a montipora eating nudibranch problem a little while ago and I think I got em all, just paranoid now, and figured theres prlly a great little fishy that would serve to protect from any future pests. I was thinking of a yellow "choris wrasse", or something of that nature

This would be going into my 125g with:

-skunk clown
-black perc clown
-desjardin sailfin tang
-purple tang
-square anthias
-carpenters wrasse

for a better idea of the setup of my tank see my thread in my signature!

Thanks!

With that mix of fish, you need something that can clearly hold its own. I'm thinking it would be a good idea to add one of the larger Halichoeres species, not a small one such as the yellow coris. The only thing holding me back from recommending a Christmas Wrasse is not knowing what you have in terms of ornamental shrimp and crabs.

At the moment i only have a pair of cleaner shrimp and and good amount of blue leg hermits and various snails for a CUC

I wasn't aware that there were any fish that ate Nudi's.
Not reef-safe fish, anyway.

Fish aren't really a good bet here. Can you remove the infested colony and treat it in a separate tank?

According to Blue Zoo Aquartics the Sea Grass Wrasse could help control these but might pick on shrimp. My cleaner shrimp are fairly large so i just wanted some input from people here before i possibly put my shrimp in danger. The fish doesnt have to be this wrasse either i just wasnt sure if anything was both reef safe and ate nudi's. Thanks in advance.

I believe i have managed to get rid of all the nudi's the fish would be more of a preventative measure to cure my paranoia that they might return....its been about 2 weeks since i have seen a nudi but every tiny white spec i see gets me nervous

The only fish I'd recommend to try to tame the issue (never a guaruntee) are, like I said, the larger Halichoeres or a Pseudocheilinus. The problem is that they're obviously capable of doing damage to the shrimp should they decide to.

Thanks!

The wrasses of the Halichoeres genus are known to eat commensal flatworms, pyramellid snails, various nudibranchs, polychete worms, and small ornamental shrimp. As far as nudibranch control, large or adult fish would be less effective than small or juvenile specimens. The smaller wrasses are more easily able to maneuver and position themselves to access the nudibranchs. I have a H. melanurus, and I love the color; behavior is similar to a six line except less aggressive overall. Some would consider the Halichoeres wrasses not reef safe because of their affinity for small crustaceans. There are exceptions to the rule though, as every individual is different. Seeing as it will be the last fish to be introduced, that should stimy some aggression.....at least for a while.
