Snail Identification?

[Warpigdave]

Anyone know what type of snail this is? I’ve started to ser a few of them every morning. They’re pretty small.

Need a side shot too. Is it pointed/cone shaped? Looks like a trochus from above.

It’s a bit flatter. More rounded.

Size? It reminds me of a Collonista snail (known to hitchhike and are harmless algae grazers that breed somewhat rapidly). From my experience, they are usually smaller than pin heads.

A bit Smaller than a pencil eraser. I was thinking Collonista, but was making sure it wasn’t the tiger zoa eating ones.
