cause ones less than 3 inches do not have a large enough mantle to suport theirselves. They need heavy feedings at least every other day. every day would be better, use DTs phyto plankton. IMO, thats the best. you can bowl feed it too so that not so much gets in your tank. take out some water and put it in a bowl with the clam, put in some DTs and leave it there for about half an hour. dont add too much or it could choke the clam. then afterwards take the clam and put it back in your tank and then discard the water. however, unless the clam is attached to a small rock or a clamshell, this would be difficult. cause you cant realy take out a large rock. in this case, you are jsut going to have to make sure that you feed your tank often but not so much to mess up your levels the tiniest bit. do not squirt the clam with phyto with something like a pipette, this will cause a negative respost and cause the clam to just throw it all back up.
