No experience with Pygmy clams but I guess it wouldn't be a problem.
I have a Anodonta cygnea or similar specie in my koi tank for almost a year,
they are sold as water filterers for ponds. Most petshops seem to have trouble
to keep them alive for more than a few months, no idea why. They filter the
water (too bad I can't find of what exactly, except green water) and mine is
doing well apparently so I'm thinking to get more when it's pond season
again. Some Anodonta species can get very big (over 5 inch) and sometimes
they like to crawl through the tank, uprooting plants and pushing stones
(they're strong). I've read this can be a concern but mine only crawled and
investigated the tank when it was introduced, and hasn't moved since it
found a good 'parking spot'. Well even if it wants to dig and move it's not
a problem for me since it's a koi tank and although moderately planted
everything is 'koi-proof' so can't do any harm. These large species fry
are parasitic to fish (lives off the fish slime), but as far as I know the
little clams are all livebearers, so you don't have a problem when you have
more and they spawn.
