I have a large maxima clam in my 72gal reef. It sits on the
LS with 4x65
PC lighting. I have had it for almost a year now and it is doing great. I just lost my Crocea to some type of worm infestation. It was also kept under
CF lighting. Unless you have
MH, I would stay wasy from the super-colored clams, but
CF has been working great for me.
