I just bought a 1.5" Squamosa yesterday and trying to find him a happy place in my 90 gal corner bow front. Lighting: Coralife Aqua Light PC, 2X65 W 10,000K CF and 2 X 65 w actinics. Plus clamp on Coralife AqualightPro MH 1 X 150W, 10,000K. Should I place him higher up closer to the MH and on the LR or in the sand bed. Only concern is that these tanks are deep, 2 feet or more, so don't think the MH can reach him down there. Any recommendations. Does this clam do well on a hard surface?
