Coral eating snail

[John3]

This snail was hunkered down on a branch of my torch for a few weeks. I noticed the the heads he was by started to die off, but didn’t think anything of it.

last night I came down in the dark to add some water and took a look in the tank. To my surprise this snail was on the top of a torch head eating away.

I haven’t seen a snail like this before. It could have hitchhiked one with some gulf live rock, or possibly came mixed in with a purchase of snails.

Any idea what kind of snail this is?

It’s about a 1/2” wide. The color is more reddish than the pics show. Also the snail was slimy to the touch, like it had Coral slime on it.

Looks like a turbo. Probably eating the dead coral flesh.

Never had any kinds turbo eat dead coral for me. Looks closest to an astrea turbo and mine don’t munch anything but algea.

Looks like a trochus

Not a Trochus snail. Banding is not correct and opening is too rounded. Trochus snails have a flatter opening, more parallel to the base of the shell.

The only time Ive seen a similar shell and one that ironically house a snail thatalso eats coral is that of a Whelk snail

Whelks look like Nassarius. Or at least the ones I’ve seen do.

Somewhat similar but have a longer tattoo patterned snout and a protective flap on their tail

Wow. It is different looking than any trochus, astrea, turbo, or whelk or nassarius. that I have ever had. And I have never seen a snail on a torch or euphyllia. If your torch was sick or dying, then that would probably explain it, because snails will eat dying stuff. But if it is a torch pest, that would be very interesting. I hope you find out what it is. I think there are some snail experts on this forum who probably can ID it.

As soon as I put this snail in my dump my torch recovered. I did end up loosing 1 head. I’m still convinced it was eating my healthy torch. It was living in 1 spot on the skeleton during day like it was it’s home and then feasting at night. That habit reminds me a lot of a whelk but I’d agree it wasn’t a whelk.

I was down in the dump last weekend and found this snail had died. I do till have it’s shell.

take the shell out and store it in a dry cotton lined or soft paper lined container for protection and later identification, just because it may be related to popular grazing snails does not mean it was a grazer its self
