Strange Night Creature

[texasdivegal]

I found these ALL over my tank last night. There are 1000's of these guys.

They move like a snail and stick like a snail too.

Does anyone know what exactly these are? Are they good or bad?

Any chance of getting a larger pic? Probably is some type of snail.

Looks like a species of pyramidellid

I believe Steve is right. They are a parasitic snail that feed on clams and are very prolific.

how do I get rid of them

I don't have a clam that they are eating.

Will they hurt a torch coral?

I have a wrasse in the tank. Why doesn't it eat these things?

Fairy wrasses won't have any interest in snails, they are not predaceous in that regard. Pyramidellids will also infest other bivalaves, univalves and feather dusters (Shimek). The best means of control is removal as they are capable of asexual reproduction. Unfortunately the wrasse you have will not allow for the addition of the wrasse that may help you with this problem..
