I have a few clams in my tank. Namely 2 deresa, one squami, one gigantea, and one hippopus porcelanis. I also have 2 corocea, that I have perched on the rocks. My question is, how deep can they go in an aquarium running 2x250 metal halides? The tank is 120 gallon, and the other clams are growing like crazy at the bottom, and some the higher rockwork is prime real estate. Anybody have a suggestion as to how deep I can place them?
