The reef tank has had few survivors so I'm shutting it down and moving forward on the gibberosa tank. After reading all the input I am staying with the plan. With the larger rocks going in I can create territorial divisions and some hiding spaces. The bigger tank and frequent water changes may facilitate faster growth. We shall soon see. My lighting may not be quite as dim as I had planned but that's short term. Longer term I'll get some other lighting to go on the tank. I have 2 - 80w T5 HO's on it right now and it's pretty bright.
