Strange red critter

[Sam25]

Please help ID this. Pretty terrifying and pretty at the same time. I want to say it’s the size of a dime-nickel. It’s purple with two orange dot. It’s living underneath a monti plate when when slight tap of the glass it retracts in maybe a tube?
Only seen it at night. I’ll try to take one in the day time if it’s out

Here is another shot. Not sure if it’s any clearer

huh, not 100% sure... BUMP.

Maybe some kind of mollusk?

Any iratation from the coral?

can’t tell from the coral but I do Linda leaning into the mollusk theory.

googled a bunch of mullusk and what I guess that it may be a some sort of thorny oyster. But I’m viewing it from the side.

it looks like the dark purple is the inside of the oyster from one of the pic and the light purple with the orange is maybe the skirt of the shell. Also I do see “eyelashes” little tentacles bellow the light purple skirt. So it’s possible. A little less scary now that it may be a oyster
