Not to be rude, but I would think it would have been faster to research online as opposed to asking that question here, you could have had all the information you wanted by now!!! That's what I suggest you should do, research online how to care for clams, you have access to far more accurate information. In any event, here are a couple of sites you may want to check out: http://raccoons0.tripod.com/raccoons/id9.html; http://www.aquariumfish.net/catalog_pages/misc_critters/clam_fresh_water.htm
I hope this helps you. Good luck to you! ;o)
PS: I'm curious as to why you need at least 7 people to answer the question???? hmmmmm

i have both freshwater and saltwater clams...
1, freshwater clams will eat left over food particles in the water. By using a particle food like tetra color bits when the fishes peck at it, it breaks apart.The clam uses the sphyon to suck the water.
My saltwater clams, i use zooplakaton soultion that the clams filter though. Also be using algae waffers when my SW fishes peck at it, it also breaks apart.
2- no, i keep my FW clams in gravel, and my SW clams were just fine in a bare bottom tank, though no i have them in live caribbean sand.
3- They have a muscle or lip that they extend and push under them which allows them to move.

1.They will eat anything that falls to the bottom of the tank like pellets or bloodworms.
2.Clams filter feed, which means they eat microscopic plankton, not sand.
3.Clams move by using their tongue to push themselves along the sand.

Hard-Shell Clam
Mercenaria mercenaria
(A.K.A. Northern quahog, Hard clam, Littleneck, Cherrystone,
Chowder)
Key Distinguishing Markings:
Shell heavy, thick and strong.
Outside color grayish, sometimes tinged with brown or tan.
Shell sculpture of numerous concentric growth lines with smooth
area near middle of shell.
Interior white, usually with a splotch of purple stain.
Interior margin of shell with crenulations (fine teeth).
Size:
Adults can grow as large as 125 mm (5 in)
Sexual maturity is reached at a shell length of 32-38 mm (1 3/8-1
1/2 in)
Various size groups have distinct common names:
Button: <1 7/8 in
Littleneck: 1 7/8 – 2 1/8 in
Topneck: 2 1/8 – 2 3/8 in
Cherrystone: 2 3/8 – 3 1/8 in
Chowder: >3 1/8 in
Distribution:
Hard-shell clams are found along the coast from the Gulf of St.
Lawrence to Texas.
In Maryland, they occur in higher salinity waters (>15 ppt),
especially in the Atlantic coastal bays, with smaller populations
in southern Tangier and Pocomoke Sounds and lower Chesapeake Bay.
Habitat:
Hard-shell clams occur mainly in bays and estuaries along the
coast, from the intertidal zone to depths of about 18 m (60 ft).
They are found in a variety of substrates, but prefer sandy
bottoms, especially with shell.
The shell protects the more vulnerable smaller clams from
predators.
The clams live buried only about 1 – 2 in below the bay bottom.
Food Preference:
Clams are filter-feeders, straining microscopic plants (algae)
from the water column.
Because they are buried, clams use siphons, which act like
snorkels sticking out of the bay bottom, to draw in water and food
and expel wastes.
The food particles are filtered out by the gills of the clams and
transported to the digestive tract by tiny hair-like cilia.
Spawning and Development:
Hard-shell clams are capable of spawning from May-October, when
water temperatures rise above about 23°C (73°F).
The gametes are released into the water column, where
fertilization occurs.
Females can release as many as 16-24 million eggs per spawn, but
this is highly variable; the average is about 7 million eggs per
spawn.
After fertilization, shelled larvae (sing. larva) develop. They
swim in the water column for about 2 to 3 weeks, feeding on
planktonic algae.
Water currents distribute the larvae around the estuary.
Mortality is very high during this stage of their life history.
As the larvae get older, they begin to resemble little clams.
Eventually, they develop a foot which they use to test the
substrate for a suitable place to settle.
After they find a good location, and if they large enough (~ 0.2
mm), the larvae undergo metamorphosis, when they change into the
juvenile stage by attaching to the substrate with thin byssal
threads (like a spider spinning a web, only simpler), losing their
swimming organs, and developing gills and siphons.
Eventually, at a size of about 7-9 mm, the juvenile clam loses its
byssal threads and digs into the bottom.
Although clams have a foot for digging, they remain in the same
general location for the rest of their lives.
Hard-shell clams in Maryland reach the legal harvesting size in
about 3 years.
Clamming Tips:
Clamming is a popular recreational activity in the coastal bays
behind Ocean City and Assateague Island.
Clams can be caught by raking or treading (feeling for the clams
with your foot), especially in sandier areas.
No license is required for recreational clamming but there are
restrictions on the daily take and the minimum size that can be
kept.
For current regulations (both commercial & recreational), see
Maryland's updated regulation page.
Fun Facts:
Hard-shell clams can live over 40 years.
This species is enjoyed in a variety of culinary ways, such as
chowders, clam bakes, and on the half shell. Clam chowder may have
been the first American soup.
People aren’t the only species that eats hard-shell clams. A wide
variety of predators, including snails, crabs, shrimp, starfish,
fish, and birds consume clams.
Herring gulls will carry clams into the air, and then drop them
on hard surfaces such as rocks and parking lots to break their
shells, allowing access to the meat.
Aside from food, Native Americans prized the shells of hard-shell
clams for making wampum beads. Wampum was used as a form of money,
hence the Latin name Mercenaria for this species.
The shells were also used for making tools such as scrapers,
knives, spoons, and hoes.
The hard-shell clam population in the coastal bays has only
existed since the mid-1930’s. A hurricane in 1933 created the
Ocean City Inlet, which allowed the ocean to flood into the
then-brackish bays, raising salinities and providing a suitable
environment for the clams.
