you're everywhere! jerkiness aside, the clams demanded that i underfilter according to my preferences. my advice is now to avoid clams unless you're going to have a poop tank with circulation and no filtration. they die in water that is filtered to visual perfection. spot feeding combined with filtration is only going to ensure that your clams spend a long time starving to death. my experience is that i started with three dozen clams, and after countless guess and tests, i have zero. i know how to keep them alive and mildly active (for a clam lol) but i dont like what i have to do to keep them alive, it sacrifices the pristine image i strive for. thanks again for all the help! clams are best kept in the wild!
