I think I'm ready anyway.... what do you guys think? (actually not getting the clam for atleast another month or two... or three... but heres what I have so far) I have a 40g tank, clams "bed" is about 6 inches from the surface of the water. 2x96 CF lights, 1x70 14k MH lamp... thats about 6.5wpg I think clam "bed" (I think I'm saying that right) has 1/4-1/2 in of live sand on top of an almost flat rock (it dips down in the middle.... kinda like a bowl). I'm leaning towards a T.Crocea Honestly this is my first reef tank and I wouldnt even experiment with the idea of a clam if I didnt have my b/f and his family teaching me everything they know. His dad has kept just about everything in his tanks at one time or another (he currently has 8 tanks running totalling about 600gal, the largest being 180) I've been reading about Crocea for about 6 months now so I think I know what I'm doing. Temp usually stays around 78f. Mod water flow.
