I am looking for a couple more africans to complete my tank. I currently have the following, bumblebee, blue johani, yellow lab, and some kind of a blue cichlid (sorry dont remember the name), and an african clawed frog. They are all around 4" in size. The tank is a 75 gallon with a rena XP3 for filtration. My water out of tap is around 7.8 and really hard, I use buffering substrate to get the water up to 8.0 to 8.2. I would like to add 1 or 2 more african cichlids that will help set the tank off. I wil post pictures up sometime soon but for now I am open to suggestions.
