Is this a tiny clam?

I literally have never seen this before it just showed up on my glass today… is this a tiny clam?

My guess is it is a snail. I don't think clams tend to attach themselves to the glass like this.

Not pictured but it definitely has a foot like a clam and it looks to have a shell with two sides.. tbh it looks more like a mussel when i look at it from the side

Is it attached to the glass by tiny little threads?

I dont see bissel

threads but it might be because its so small tbh

Watching it in the flow its attached to the glass basically at the hinge as it flips back and forth on that point

Certainly looks like a Bi-valve. Cool.

Just an update, I was staring at it in the dark with a flashlight and I did see tiny threads connected to the glass! How funky I have no idea what this thing hitchhiked in on but Im curious how well itll do in the tank

Agreed, thats a little filter feeding bi valve. Really cool.

I've had little hitchhiking Mussels start out that small, and grow fairly large in the tank. They seem to do especially well when attached to a rock.

I actually saw another climbing out of the sand just now… i wonder whats prompting them to come out… a really tiny one attached to the glass but i saw it get blown away by the flow

It just attached itself to a hermit!

I am really surprised that hermit crab didn't make a snack out of its little hitchhiker!

It almost looks similarl to this guy I found in my table the other day, mines about 3/4 inch long no clue where it would’ve come from

Well the flow blew it straight to the hermit and it just latched on! I guess ill see if it made it later haha

Wow! I hope mine actually grows that large im pretty invested in this guy now

I think what we came up with was that it was a Atlantic ribbed mussel
(Geukensia demissa) that is the closet thing we could figure out on my thread! I would thing it could be the same and mine has moved three to four inches in the last couple of days

Geukensia has raised ribs coarse ribs yours looks like it has fine ribs that your fingernail wouldn't catch if you ran it along the shell. Also an Atlantic ribbed mussel wouldn't come with tropical reef rock did you add something from the ocean outside the tropics? I'm still pretty confident it's a Brachidontes exustus or a closely related Brachidontes species. But I'm a hobbyist not a marine biologist so I bowed out haha.
