Anyone know what this? Barnacle, scallop, limpet?

[TylerJaid]

Hey everyone I was just looking at my tank tonight and saw something new on the rocks I had to pry fairly hard with a tweezers to get it off but does anyone know what it is good or bad? I put it back in for now just not knowing what it is!

I mean it definitely looks like a scallop and it’s certainly a bivalve. How did you find it exactly? Was its’ opening facing down like in the photos?

It was like the bottom photo, with the “bottom” or opening of it pressed on to the rock, it was pretty difficult to pry off. I don’t want to kill it just to kill it unless it is something bad… just trying to figure it out I have no clue.

Obviously some type of harmless bivalve, put it back where you found it in the same orientation.

That’s what I did for now, don’t know where it came from I haven’t added anything in a long time and just didn’t want it to spread or make more somehow he’s back in there if still like to know what it is can’t really find anything like it anywhere

Some bivalves use their foot to dig into sand or bore into rock which is why I asked. But their foot comes out the “front” not the “back”. Or rather the “top” not the “bottom” as we would think

This looked to be where he was attached to the rock I put it back and it dad attach back onto the rock but I have not seen it move or do anything at all

bivalves don't do much really. I had a lot of them on my live rock including a scallop. Open, close, thats about it. Many of mine look like rock, but you can see a seam, and if you touch them they'll snap closed fast.

Looks like a scorched mussel.

Well it’s like not a boring bivalve then. Cool stuff! Hope it lasts a little bit if’n you want it to!

Looks like something in a book about invertebrates I have somewhere the common name is turkey wing I believe a type of clam?

IMO - that's a limpet. Bivalves have two valves (shell halves) and don't stick to rocks except with byssus threads.....

edit: I missed the second image.

To me it looks like an abalone……..

This is what made me say mussle. I believe that's a side view with both top and bottom shell in the picture (I could be wrong). If it's a mussle would ripping the byssus threads kill it?

I would like it to I’m going to see if it fully reattached when I get home and not mess with it if so!

It does look similar I looked them up I’ll see if it lives I’m hoping it does it’s very small!

I think you might be right on a mussel what kind who knows I’m hoping it is okay and I didn’t kill it but I guess time will tell, but I think it may be a mussel it did have to “halves” but no apparent opening

I will look into them and see but I think it may be a mussel like Keagan said! Thanks for all the help hopefully he lives and I can get a id on it

So whatever it is it did reattach, it is attached on the side face away from the picture
