What kind of clam is this?

[Dorinda]

I've had this clam for about 3 years now. I'm not sure what type it is and was just wondering. Thanks for any help.

What kind of conditions is he in? (like lighting etc) From what I gather a derasa you had for 3 years should not be 3'', but much larger. On the picture I cannot see any active growth (white edge of the shell), but it could be the image quality.
