Does this look like a milli killer to you!?

Something is munching on my Blue Millipora, the rest of the coral and the rest of the tank are in GREAT shape. It's recovering from being eaten. When I look at the coral, no matter what time of day, the only thing I see out of the ordinary is this guy. Never seen him in here before and never had an issue before. Coincidence?

I can't remember the last time I saw a thread where a snail was responsible for eating an sps coral. It's usually Nudibranchs, Flatworms etc, but I guess it's possible. It kind of looks like a harmless Collumbellid snail though.

If they're not feed well, they will eat whatever is available, crabs will do the same thing.

So your saying that if there's not enough algae to go around my Trochus snail or my Astrea snail will start eating my Sunset Montipora or perhaps my Birdsnest before it starves to death? I highly doubt that... This is another thread I don't think I've ever seen before either. There might be some snails that do in fact do this, but you can really lump them all together like that. Pinpointing the species would be much more helpful.

Just as an example, there's a few in the link below that are known to eat corals.

There are snails that eat acropora flesh.

I don't doubt that, but which ones and do they look like the OP's?
