Water level is 17" and its under dual 400 watt Halides. I don't think light is an issue anywhere in the tank
It just won't really attach anywhere like my other clams have but it seems really happy in the sand. Everytime I put it back on the rocks, it falls or gets knocked down in the night. I have no idea by what but I am tired of picking it up.
I think I will try the rocks one more time though.
Thanks.
