Which wrasses eat those tiny clam-attacking snails?

[GoSUV]

I am looking to add a wrass to my 125g system, in order to control those tiny clam-eating snails, with a plan to add a clam later. I know I have those tiny snails in my system because I see them at night. These tiny b@stards are hard to eradicate manually.

Which kind will do this primary job, without being:
1) too aggressive;
2) harm to my LPS corals (torch, hammer, fungia, brain);
3) too finicky to feed other foods;

I know the yellow coris wrass will do such a job, in addition to controlling flat worms. But it has a habit of jumping and sleeping in sand, stiring up sediment. The primary worry being that its digging activities will irritate my sand dwelling LPS corals.

The sixline might also do such a job, but from what I gathered, it is pretty aggressive.

The eightline and fourline might seem good candidates, but these seem to be not very common and I haven't been able to find much info about them.

Any other fish(es) or inverts will help control such snails?

Will these wrasses also harm my pods population because I also intend to add a mandarin to my system and don't want extra food competition.

Thanks in advance.

I was going to suggest Yellow Coris when I read the title. I have one, and he is a damn cool fish. Gets along with my clowns and Anthias great (only fish so far). The only time he is in the sand bed is @ night, other then the first time introduced to the tank where he was frightened and buried himself quickly. I wouldn't think that he would be doing enough stirring of sand to really worry about it at all. Just s small sand spray, which is really cool, when he tucks in for the night

I also had a 6line that wiped out a flatworm infestation i had in my old tank. He was cool, and pretty calm with the fish in his tank, i have heard of others having aggression issues though.

Yes, they will eat pods as well. They hunt constantly and are always picking at the LR.

do you have a pic of the snails? they may not be as bad as you think.

Pyramid snails are what you are talking about. I found the Christmas Wrasse to be a cheap way of eradicating these pests. Looks really cool and sleeps in the sand like some other wrasses. I have no idea where he sleeps though as he is about 1 1/2" and doesn't make a mess.

I paid $25 at a LFS

Radiant wrasse, Halichores iradius. They are really attractive and eat all of those nasty little creatures. No matter what wrasse you go with there is going to be some damage to your pod population.

anything in the halichoeres genus should do the trick i keep one in every tank i ever owned there really good at eating many pests

Wrasse sleep at night, snails feed at night. I've tried - three different sixline, a green wrasse and a mystery wrasse. None of which Have I ever seen eating these nocturnal snails. Your best bet is a toothbrush.

Even on occasion the snails climb the glass during the day - always left untouched - the wrasse rather chase the pods on the rock.

If you do find something, I would love to know.

I'd ask on the Tridacnid forum. They can tell you everything you need to know (and more!) about pyramidellid snails.
