REEF NERD
First you have to get a healty calm to begin with and have lights strong enuff for clams.If you have fish in your tank that will be all the food they will need.Heres a bit out of Knops Giant Clams book
"We have to keep in mind that only a samll percentage in the range of one to two per cent of the food we feed is actually used as a food and the rest eliminated by filtration system most of it by the skimmer.Such a degree of over feeding is unavoidable to obtain the food denisty necessary to satisty the food requirement of all the animals.This over feeding should be kept as small as possible.Corals and clams are adapted to a slow food uptake and therefore a daily but samll amount of food seems to be better than weekly and large doses.Clams do not only take up the food we introduce to this purpose but utilize other matter as well as for example waste products of fishes present in the tank.Altogether the food reqquirements of clams is so samll that a special feeding scheme for them is superfluous if the tank is populatated with a fair number of fish especially if corals are regulary fed.In such a case a special food destined for the clams couls even unbalance the whole system.Another situation however is caused by the symbiotic alage living in the siphonal mantle of the clam.Their population density per square unit is about ten flold in comparison to corals."So in other words no real need to feed them.
