after i introduce my monti to my tank it was flaking. then i tried moving it around and i found the best spot for my monti is up high right under my koralia where all the flaky stuff gets suck in. after couple of days it got better and is growing pretty good now under my 2x65 pc light.
I think i know the answer to my question..My tank has been having low mag around 1125, Kh of 10 and calcium of over 600.. So the problem is my mag keeps going up and down causing the monti t die..
