I never realized this could be a problem, there's millions of those guys in my tank, though in all fairness I haven't looked closely at my clam in about 3 months.
The only fish that I know of that actively hunts these critters at night is a copper band, would you ever consider getting another? Why did you let go of the first one? Mine never stops hunting and I still have a noticeable population of them though, so even with a Copper Band you're not going to eradicate them, just reduce their numbers.
