pyramillid snails

[saltyflash]

I have a great number (hundreds) of tiny little snails on the glass and coral bottom that resemble nassarius snails in the shape of their shells. I am assuming these could be from my 5 highly reproductive nassarius snails that lay hundreds of eggs every couple of weeks. Can a 90 gallon possibly benefit from so many snails... can't imagine it.
So, my questions are these...
First, are these what are known as pyramillid snails? Are these that beneficial that I should just let nature take it's course? If I do need to pare it down some, how? Who eats them besides the six-line wrasse? And... is the six-line a peaceful fellow or does it
"harass peaceful fish and shred fins and remove scales while harassing smaller fish with it's large canine teeth".<--quote from marinedepotlive.

Yeah, I know, a whole bunch of questions but who else am i gonna ask besides the gurus of AC.

just keep them or just put a lettuce in there and leave it over night and there will be heaps of them on it and just throw it away thats what i use to do

6 lines are little terrors, to agressive for the adverage community tank.

If they are pyramidellids, then they will look more narrow than a nassarius. The shell shape is like a cerith. Because nassarius have a planktonic stage, and pyramidellids don't, it's more likely that a plague will be pyramidellids. As far as I know, they don't go after corals, but will suck the juices of snails and clams.

I haven't kept any of the suggested wrasses, so I can't say much about them.
