Id this snail

[StickFish]

I have 2 of these in my tank. Ive had them for a few years, they havnt seemed to bother anyhting. They move over the rocks and glass and appear to be detrivores.

Can any1 id them, are they a threat to softcorals or polyps?

It's an Engina species, which is a small buccinid whelk. Hard to tell which species for sure from the single photo, but it's probably Engina lineata.

There are a couple other species that are similar, and a morph that shows up occasionally which appears to be intermediate between Engina lineata and Engina zonalis. Yours actually looks like one of the intermediates.

Cheers,



Don

...and no, they're not a threat to corals, either soft or hard.
