I think that's what I have - but the DIBS guy thought they looked like "Nassarius #1" - haven't heard back from him about a positive ID yet. said:Misty,
Hey there, I thought you were the one with Cerith sp #1, but if you could post a picture of them I could try to confirm what you have.
Serk does have the "Strombus grazers" in his tank. But ISPF has the wrong ID on them. They are a Columbellid snail of the genus Euplica.
More information on them can be found here:
