this is my first malawi cichlid tank and am looking for some advise on a couple of things. i have a 120 gal
tank its 60"L x 25"H x 18"D. going to use a ca1000 canister filter, a ca
-900 power head, and a m300 heater. going to go and pick up a bunch of lace rock tommorow. trying to decide what to use for the substrate though, sand or gravel. not sure which is better for the fish. i have never used sand in a tank before so not sure how complicated it makes the cleaning process. i also need some help deciding what kind of light and how much to put in it. i am making a wood canopy for the tank so i have plenty of options for the lighting just not sure how much or what kind. i dont think that i have forgot anything else, if i have please let me know.
