The family and I went to the beach this Sunday and while sifting through the sand,i came across a 1/4" clam in the sand.I ended up taking it home and set up a very small tank with a sponge filter for it. Now, this is the first time that i keep a clam.i thought i'd try to see how big it'll get.I've done searches here and i can't find anything on raising them.anyone have specific details and maybe know what kind of clam this is? It's like a light -brown,yellowy shell.
