is this a trochus snail?

I noticed a small white blob on the base of a hammer last night. At first I didn't think it was moving, but it does, slowly. My first guess was a flatworm of some kind, but when viewed from the side it seems to be quite triangular shaped ^

I've seen the 5 Trochus snails I have spawn a few times, but assumed nothing would survive due to the filter/skimmer/fish/uv.

That was fast! Thanks, nothing to worry about then

Next question, while I was studying the limpet I noticed little hairs coming out of the coral skeleton. At first I thought it was hair algae, but noticed they retract when the coral is moved/knocked.
I've got quite a few bristle starts the live in the rocks, but these don't look the same.

These seem to have a small head and two 'feelers' that poke out.

From what I can see in your pic I'd say no. Mine are more cone shaped.

They look like harmless spionid worms.

Not sure it's the same snail as my first post, but this is definitely a baby trochus!
Probably 5/6mm across

I have been noticing lots of little tint baby snails in my tank. My guess was trochus by their shape

The other day I did a large water change. While I was sitting watching the tank I noticed a small white cloud. I watched for several minutes more and saw that it was a trochus spawning. Was really cool
