I know this might be a long shot but I visited this LFS
of mine that is close to Raleigh NC and he has roughly a 1600 gal
reef tank that I wish at the time I had my camera with me! http://reefkeepersaquarium.com
This guy was no BS. He buys straight from the divers and has the most awesome reef tank I have ever seen.
I am sure he will work with you on rock, fish, coral, lights, etc!
I went in with over $500 and he would not sell me lights because of the size of my tank. BTW I only have a 29 gal
FOWLER. It's worth a shot. In the left corner of his reef tank he has a giant clam! I don't know how many LFS
keep this critter but he says he has had it for over five years, very nice. Anyways Good luck with your tank!
