cool, I figured the more variety the better. Thanks for the offer on the clams. I might be working down there this week but I'm not for sure, I'll pm you if I am. I thought about him possibly going after tridacnas but I want to try to stick with PC lighting on that tank so, I wouldn't be able to do croceas or derasas anyway. I would love to have a gigas though, maybe in another tank.
