Hmm...this could be an interesting experiment with lighting and octos then. If I had another 48" tank, I would just switch the brighter lights to it, but the longest tank I have is a 40 gallon, which is about a foot short. I don't want to sell this fixture, so maybe i'll just put the NO flourescent strip bakc in it from when I bought the tank. I think i'm gonna get the octo from either Marine Depot Live, or Saltwaterfish. Not 100% sure yet, but i'm leaning towards MDL. I need one that is active, and out all of the time (well, the majority) as I have about 100lbs. of live rock in this system, so if he wanted to act like a dwarf, he very well could. I'm going to have to move my clam, YWG, blue green reef chromis, and blue tang (possibly).
