Hello, I just finished moving to my new place and setup my tank again. My last setup I had tetras, but now decided on setting up a small African cichlid tank for the first time. This is a 46 gallon bow front with two medium size Texas holey rocks. I will put a either a blue or black background whenever I can find a place to get one. I would like some helpful hints and advise since this will be my first cichlid tank. Should I add more Texas holey rocks?
