I have a 75 gallon freshwater tank with no fish in it. It has been running since late november and i am ready to start putting in some fish. I originally thought i would have a large community tank with german rams, silver dollars, guaramis, and tetras. Then I saw a cichlid tank with a frontosa in it with ceveral other african cichlids. My question is if Frontosa can be put in a tank with new world cichlids like convicts and severums. My tank is currently at 81 degrees Farenheit and PH at 7.2, i am aware i would have to raise the PH to more alkaline levels of high 70's or low 80's (correct me if im wrong). Help would be appreciated.
