Alien in my tank???

[dt509]

I've posted a few pics of this thing and nobody seems to know what it is. Today I took it out of my tank to get some better pics of it. Maybe these pics can help someone ID this thing for me.

thanks

is that its tongue hanging out in the top picture? Some type of clam possibly?

I tried to attach a few pics but I could not do it, so here are some more. the fist pic is the top of it and the second is the bottom.

I think it's a tail, when it moved that was toward the back and under it

That is very strange...I have no idea, but here are a couple of sites that might help.

Looks like some sort of baby cockle to me...

looks like a clam to this uneducated guy. Whats it taste like with tobasco sauce on it?

At a glance they look exactly like what I have on numerous rocks in my tank. Mine turned out to be small clams of some sort. Many of them seem to be migratory.

It is a scallop. They will occasionally swim around the tank by clapping their halves together. Once they find a location they like, they tend to stay put.

The "Foot" is another way that they can maneuver themselves around, or attach themselves to something as necessary.

I'm sure it is a scallop. You'll need to provide phytoplankton for it to survive. It doesn't need light...in fact it probably doesn't like the light much.
