I finally got the new custom tank for my cichla, 72"x30"x18". I now have to decide what type of substrate to use. I know I am gonna paint 2 sides and the bottom black, so I wanna do black substrate, I love the look it gives the tank and also the colour it brings out in the fish. My question is whether I should go with gravel or sand, I am not gonna use much either way because of the shallowness of the tank, and I am leaning towards gravel because I can see the sand getting kicked around and constantly being cleaned out of the canister. Have any of you guys used 3m colourquartz? and if so what are its characteristics compared to sand. Also, what size do you guys think I am gonna have to take the monocs outta here, I am hoping I will at least get a couple years because I can only get another tank when I move out....
