I'm not sure what lights they had them under but my LFS
had one in a display tank or "grow out tank" as they called it and it was beautiful. I saw another site that told how to check a clam at a locale shop and this one reacted as the site said it should. The colors were bright, when I looked down into the tank and the light changed a little the clam reacted fast. The more I get from you guys these other sites and stuff the more I am thinking my LFS
is one of the better ones. They aren't looking for the sale so much as the hobbie, creatures, and hobbiest in mine.
