Update time...today I picked up a crocea clam, since I now have the lighting to keep one, and also, since it's the smallest of all clams, it's suitable for my tank.
Ok you all, I got a little bored last night, so I reaquascaped the entire tank to give myself more floor space for the clam and for when I get a lobo brain later on. The layout is a semi-circle type design. I'll post pics when I get out of physical therapy, the lights will be on by then.
Smitty, I really really like the way you did your aquascaping. I plan on doing the same thing eventually. It looks like a window into a specific piece of the reef and not like you tried to simulate the entire reef in the tank. There is a MASSIVE tank in Iceland that follows the same concept, it is something like 1200 gallons though.
