No clue ?

Howdy,

What is this little fella ? Loads underneath rocks and in crevices

Near the center of the photo?

Looks like a limpet. I've not had trouble with them, but some folks have reported that some limpets may snack on coral.

Thanks - did some research with the ID and it's most certainly limpets. I've read they're beneficial to an extent and some can nibble sps mostly harmful tho. I've read they're also signs of healthy tanks - so that's good.

Thanks !

Can't tell from the pic, but if limpet, as @Maritimer suggests, they are like snails only shallower. I have a couple approaching 1", never bothered corals.
Some had hundreds in their tank on the glass.

Yes center of photo. The tank definitely has quite a bit.. I don't know where these colonies are coming from just massive outbreak of both limpets and astarina starfish. I've always had one or two but they're multiplying like baby boomers

You can manually remove both, although limpets defy the laws of physics with their ability to suction to a surface.
