Anyone know what is this?

[ssunthar]

Found this while cleaning the sand... it looks like a snail but want to be sure and also what to know if it is good or bad. Here are some images showing both sides. Thanks.

Does it move when you touch it?

 

[ssunthar]

No, I didnt see it physically moving but, I see it at different places on the sand. I believe it hides in the sand and it apear hard (covered by shell).

its a stomatella. nothing to worry about

 

[ssunthar]

I came across stomatella in my tank in the past (see pic taken when i wondered what it was), but this one looks different.

its a limpet, another grazer

depending on the angle we are looking it could be a coquina clam (Donax)

Suspected it to be a limpet too but this guy in my tank is hard on both side and I didn't notice any soft organ. Let me try to take a closeup pic when I see it next. Thanks.

Here is something closest (as I was researching) that resembles what I saw in my tank... it is called Madagascar Sun shellfish.. not sure if anyone seen it?

Those are the name escapes me at the moment, but when a snail pulls in to it's shell, those are what closes it up.

Oh... it is part of a live snail that might have dropped when it died?

It looks like the operculum of a deceased snail. RIP snail. :)
