When you say you've moved it around, how long did you leave it in one spot before moving it again? Constant moving will tick them off. With that amount of light on your tank, I'd have it on the sand bed.
At least 1month each time I moved it. So are you saying that my light is a lot for the tank? Geez, and I was always worried it wasn't enough since it was shorter than the tank. Today when I get home I will move the Brain to the sand bed in the front of the tank.... Thanks a million for your help! Hope it's not too late to save him..... those dark brown "cracks" make me nervous it is.
