clam question
 

I found this guy moving along on the top of a rock opening down to rock is it realy a clam or something else it was moving towards a snail. It is in my QT with a new true percula I can't see it harming him. A few of my herits have gone missing out of their shells could this guy done it? If this is a clam i didn't know that they could up root them self and move once they astablished a ancor.
This is the best pic I could get with 10x macro lens it is about the size of a puffed wheat grain 0.5 inch long.

removed pic's.

Thank you,
Bill

Doesn't look like any clam or snail that I've seen. Strange looking creature, I doubt that something that size could take out a hermit crab.

looks like a scallop

I think maybe it was just quincidental that it was go the same way the hermit was. I don't know can clams be preditory?
also new pic in first post.

I did get to see him trying to bury him self in the sand the tung is white and long it must be a clam of some sort I have a couple that are inside of my rocks much bigger and they kind of look the same the shell is more rounded though and they don't seem to like bright light as the one in my rock will turn away from the light.
Also I posted a couple better pics in the first post.

Hmm definitely a clam of some kind. Likely a non-photosynthetic filter feeder, probably reef safe... I wouldn't worry.

I have quite a few of these little guys. I knew their name at one point...maybe someone can come up with it. They've never hurt anything in my reef.

The ones that are in my rock are about 1" by 0.5". Thank you guy I was just wondering because the tank has been operating for going on 4 months. Corals re growing good some better than others. I keep loosing hermit crabs though put them in and they are good for a few days and then they just disapear. I have moved almost all of my rock at one point trying to catch a flame angle to TQ it. I should have left it be as It died from the stress or the ick or both, I hate that. So I treated the tank after that quorter dose of a general aid that pet cetera plus Aquarium Polyaqua. the only things that seemed to clamp down were the herms and snails the rest of the criters in the tank it was biss as usual. I use this comibation when I QT new fish and it gets rid of any Ick on new fish that is visible when purchesed.
