Yes scraped some off and felt the under side was more snail like. It has a black foot. Not limpets , has an overall “shell” shape.

range in size from a few mm across where the largest one is the size of a quarter.

Interesting - can you take one of the larger ones and take a picture out of the water?

Yeah, with that kind of situation, jingle shells and slipper limpets are the most likely suspects, and - based on the shape of these ones - I'm inclined to agree that these probably are jingle shells.

These seem to have a small mouth or opening and i wonder if tunicates but pics hard to see as theyre somewhat fuzzy. Clearer pics may be helpful

These look like Ostracods which are flea like often referred to as grass shrimp and are scavengers eating algae
Can use clearer pics to fully confirm
Was this reply meant for another thread? I see spirobid worms and some sort of transparent bivalve attached to the glass.

Thanks!! Maybe I’ll make necklaces with the left overs..

Common bivalve that can have some awesome and unique shell colors!

Much appreciated.
Out of curiosity here, OP, how long have you had these guys, and are you feeding/dosing anything that you think may be sustaining them (like phyto)?

Lol at jingle shells.. Thought ReeferReboot was trolling me until I looked it up hahaha. Had these guys for years... I feed quite heavy and I used to dose Phyto back then for my pods. Started seeing a few in the sump walls and thought it was some kind of bivalve / filter feeder so I didn't think much of it.

No, not trolling you. I just know what they are because they can hurt like hell when you step on one on a cold winter day while heading out to go surf. I've stepped on a lot of them. They break easily and can have sharp edges.:anguished-face: I did think this was a very apropos question considering the date.:D
