Snail ID pls

[Dazed1]

I've been having a few issues with my tank for the last few months. Almost everything's gone (SPS, Acans, Zoas). Only left with my ORA green leather, BTA, Gorgonians, scoly, small colony of zoas.

I found these snails, but I've never added them to the tank. Last thing I added to the tank in terms of rock was the BTA (6ish months).

Are these "bad" snails?

Harmless algae grazers. Trochs sp. (radiatus?).

Thanks!

Shortly after I posted this, i found a sundial snail. Off to the sump!

Yes, Gerrit nailed it. It's a trochid for sure, and if it's not T. radiatus it's one of the snails in the "T. radiatus complex" like T. ochroleucus. The juveniles are nearly indistinguishable.

Cheers,
