I walked in the aquarium and told them I'm new to all this but I would like African Cichlids and I would like fish that get along with each other. The following are the fish he recommended. Golden MbunaYou want ammonia and nitrite on 0ppm at all times, and nitrates under 20ppm.
If you have an any reading above these figures, do a 75% water change and gravel clean the substrate every day until the levels are back to 0ppm.

If you have problems with ammonia going up, reduce feeding to a couple of times a week and tell us how often and how you go about cleaning the filter.

What African cichlids do you have?
Post pictures if you aren't sure of their names.
