Nudibranch Eating Wrasses

Many of us have had the unfortunate experience of combating Nudibranchs in the past. I don't wish them on anyone as they will wreck continuous havoc on a zoanthid population. Many will only keep Palythoas as a sort of proactive measure to keeping their reefs Nudi free. It is still possible, if great care is not taken, to infest your tank with Nudibranchs. They will Hitchhike on rocks without a single zoanthid present. It certainly happened to me many moons ago, I simply forgot to dip and true enough, BAM, a Nudi. I have seen them in stores on rocks without a single zoanthid or palythoa on the rocks. From many hours of just watching them, they will consume one rock, then travel to find more polyps to consume and yes, they will travel across other rocks to get to the next colony they want to devastate.

Dipping, close visual inspection and QTing are the most noted ways of preventing infestations, but a good hunter always on the prowl will also decrease the amount of time the infestation will occur. For this reason, lets create a list of known Nudibranch consuming Wrasses for future reference. Listed below are a few that I have heard of, but I'm sure their are many many more, so please take a moment to share everyone. It could truly help a fellow reefer in need some day.

1. Yellow Coris
2. 6 Line
3. Lunar
4. Possum
5. Orange Striped
6. Christmas
7. Pink Striped
8. Some have said most anything in the Halichores Family as they are serious stalkers.

is it a fact that if i see one nubi, there are many more??

say it aint so...

Not always, but the odds are for there being plenty of others.
 
Sweet, cuz I placed one in my 24 gallon aquapod. He is the only one in there with ton's of zoa's. Zoa only tank.
 
I have a dreaded nudi problem.I've tried everything to elimate them aside from breaking tank down.I'm starting to get tired of sucking them out one by one.
I've never kept a wrasse before.Which of them do you think would be the best canidate?any problems associated with them?
Thanks.

The ones I have heard the most success with are the Sea Grass Wrasse (Sometimes called Green Grass Wrasse or Green Wrasse), Yellow Coris Wrasse, Leopard Wrasse and 6-lines.

Any of the Coris family should be fine but you have to watch them and see if they are actually going after them. Its not 100% that they will do it just that they are more likely to.
 
Something else to keep in mind.... not all of these wrasses are reef safe... so anyone getting one should choose wisely if they want their inverts in the tank!
 
I had a Lunar Wrasse that would destroy nudis... He'd also destroy every snail and hermit in my tank too though... ;)
 
Here's a pic of my green coris wrasse. In case anyone wants to know what they look like.

Are the yellow coris wrasse reef safe? I think they had them listed on Dr. Fosters and Smith to add with caution. Anyone had any negative experience with the yellow coris eating corals?
