Anyone keep a coris or similer wrasse with their clams?

I have seen a few recommend coris wrasses for parisitic snail control in clam tanks. Does anyone actually do this? I am considering a clam filter on my next big system, a tank with only clams. So i figured a coris would be good to add for snail control, as the clam filter would not have other corals and such that it might pick on. Any thoughts?
 
Hi Jeremy.

I wouldnt put a coris in your you big tanks. Everything I have read has only recomended juvi's and to remove them as they grow up, because adults dont eat the snails and can potentially be dangerous. A 12+ inch wrass is not going to bother eating 1 mm snaills. In your tanks the will only be juvi's for a few months and you will never catch anything out of it. You will also though out any possibility of having a nice heard of cleaner shimp.

You seem to like fary wrass's, Why not some of them? They stay reletively small. Any small wrass will the eat parasitic snails.

PS. I guess it's too late now but if I were you I would be quarantining everything that goes into that tank.
 
I haven't got one yet. What I am thinking about doing is replacing the 125 at home with a 280 gallon tank with a 90 gallon Clam filter tank, which the main tank will drain into. I was considering adding a coris wrasse in. I was not aware that all wrasses preyed on the snails.
 
I had juvi coris wrasse that was OK with clams. Got rid of it as it got larger.

Have leopard wrasse now. Much better IMO, but a little harder to keep.

Not all wrasses prey on the snail, but most do. The snails are mostly out at night and the wrasses need to be too. I have flasher wrasse that doesn't bother chasing pods or anything anymore... it just waits until I feed the tank.
