Interesting to see little blue dots if it is a derasa, that does make it look vaguely giga-ish, but the shell and the way the mantle sits looks more derasa-ish to me. I babysat a gigas about a year ago, you'd think I could remember how scutey the shell was, but noooooooooo. I can't remember at all. Argh!

Anyhow, what I really meant to point out to you is you may want to pry off that vermetid snail (tubeworm thingy) on the shell to the left there. They multiply like crazy and will drive you (and your corals, and your clams) nuts with the little spiderweb fishing nets they use to catch passing detritus.

Do you have any side shots of the clam? I am leaning towards derasa for the ID, but I need another photo.

Even if it is a gigas, they grow relatively slow.

Here is a side shot. I think that snail is dead because I've never seen anything come out from it...I'll pry it off anyway though.

No problem. Usually the things to look for are a side view of the shell, scutes, and closure pattern.

Those blue spots sure are pretty though!
