[!] My snail eat SPS !

[Berlibee]

Hello guys,

Few months ago I found that snail in my tank:
https://www.reef2reef.com/threads/please-id-just-found.224099/

Then this snail growth, I've noticed few damaged acros here and there but very small, I was always blaming my small gorillas crabs that living inside the rock. But yesterday that snail was walking on my acro and on the morning I've noticed that this acro miss all the tissue in that spot, the acro is bright beige color so it was difficult to spot from first look ...

Today I did an experiment, when that snail started to eat around my fresh frag that was encrusted on the rock I was just waiting to see what will happen after she leave that spot.

Here is the result and few more pictures of her work, all encrusting is gone and tissue on the frag is damaged as well:

All the front side is gone on the bottom:

I don't know guys, but they're not reef safe at all @143MPCo Cheers !

If it has a hole at the apex of the shell it's likely a keyhole limpet which do eat coral.

Is that a sundial snail?

Is this same?

Is this same?

Sure looks like it, maybe others will comment.

Yeah, that looks like a keyhole limpet of some kind to me - just to add, most keyhole limpets are safe; if yours is eating your coral, then you got pretty unlucky:

It’s rare, but there are two taxonomic subfamilies of keyhole limpets (Diodorinae and Emarginulinae) that I have found research on showing that they have a handful of species in them that are either known to or thought to occasionally eat corals (I’d need to go digging through the papers again, but, IIRC, they only ate SPS , and they had pretty specific tastes/preferences).

do you know how to kill these snails?

Not specifically, unfortunately - most remedies I know would hurt other things the tank too. I'd imagine predatory snail species (like oyster drills, Murex snails, or similar) might eat them, but I can't confirm that, and they'd likely eat your other snails too.
