Hi guys I need urgent assistance, I have noticed zoas are missing especially were I have few zoas mounted on my rock work.
I.only.have a pair of clown fish in the tank. All corals are looking healthy.

I have found few snails in the tank and got in by introducing corals.
Below are.few pics of them please I'd them.

Thank you

I don't know if those eat zoas but the best thing to do is at night about 2h after lights go of take a torch and see what crawls over ur zoas if they are ontop of them im pretty sure they up to no good.

These looks like nassarius family. They are detritus / scavengers / vultures.

Yes reef save

Rather check for a sundail snail. Or coral dip all your zoa rocks. Possible to have sea spiders in between.

Nudibranches, sundial snails, crabs or bobbit worm.....Need to do some late night tank viewing to try catch the culprit.
