I love the beautiful clams posted here. I have a fairly new aquarium and on one of my live rocks, i found a clam hitchhiker. I thought he was part of the rock until one of the snails started cleaning him up. Now when I watch, I can actually see him close and open a little bit. Its pretty cool but he looks like part of the rock instead of the pretty ones everyone has posted.
I went to the show yesterday also. I was tempted to get a clam but restrained myself. The husband and wife that had those big ones were beautiful and went fast. I like the clam bake.
Mines under 1 Aquaray tile (about 150 par) but my tank also has a sun tube over it for extra overall light and spectrum. The sun tube gives off up to 800par in the light rays.
