Sand and dirt substrate tanks can accumulate toxious gases below the surface. Having a species such as a clam to dig through the substrate means that these toxins are released regularly in small amounts. Without them it's possible for them to build up in large amounts then force it's way out, probably killing anything unlucky enough to be in it's path to the surface, and maybe even have severe health effects to you if you happen to be over the tank possibly doing a vacuum or something. This is what happens in the Bermuda Triangle.

My guess would be another parasite. It shouldn't pose a problem to the meat, tho. Gill parasites are pretty common in the wild. In fact all kinds of diseases are common.

And while clams do dig in the substrate, MTS are a better aerator than clams as they move around much more. Clams are rather sedentary and only move if their location becomes too crowded.

I have golden clams in my 200 gal planted community tank. I started with about two dozen in a temperate climate 100 gal tank as that's where the specimens were collected along with other local fish and plant species. Actually water temp in the wild was 36 to 75 degrees. I simulated this by having the tank in the garage. Substrate was black sand from seachem. I used a low tech bio filter and barley filter in the sump to simulate a pond environment. Only food introduced into the tank was for the fish the clams lived off the algae in the water. the water was not green but a kind of tea color as you would see in the wild. they did so well in this set up for two year that the started to reproduce. I recently upgraded this tank to a 200 gal with a fx5 and its now a tropical community tank with temp at 78.5. when i was moving everything I found over 100 clams in the substrate. I transferred everyone into the new tank but have lost about a dozen of the smaller babies due to the lack of algae in this setup. I had to supplement with ground up algae wafers and that solved the problem. I also would like to add that they did surface before they died and with dark substrate you can see you populations bivalves clearly and keep tabs on them. I also keep them in a calmer section of the aquarium just out of the main current so i can dust the group with the ground wafers but they still get circulated water.

I personally like them and they add diversity to the tank. I would say the lower-tech you go the easier they are to keep as long as you keep you ammonia and nitrite under control with good biofilter and steady water changes. I did 20 percent every two weeks. And for god sake no meds, especially those with copper! hope this helped
