durasa

Has anyone placed their clams at the top of their tanks? I'm looking to turn my tank into an LPS dominant tank which means my substrate may not have enough par for a clam, but the top of my aquascape might.

My goal down the line is to have either a Durasa or a Maxima clam. Would they be OK with AI Primes for lights, or better with Kessils (or something else)? I plan on having a 160 gallon FOWLR tank as a reference. Thanks!
