First off I am new to this forum and am really just getting started with a cichlid tank! I have a 30 gal setup of black skirt tetras, blood fins, corys, bushynose and serpaes, also had a beautiful betta in this tank for a little over 3 years until he passed away only recently. It has been a great starter set and still cant bear to part with it. About 8 months ago graduated to a 55 gal that I bought from a friend which came with fish, blood parrot, gold severum, tiger,ruby,cherry barbs and a bushynose and 8" common pleco. Have enjoyed it so much cant wait to establish a 75 gal african cichlid tank. *** done alot of research but seems the more I read the more confused I am. Since I am not interested in breeding would it be okay to only get males, or should I go by the rule of thumb 2-F/ 1-M to ward off aggression? Other concern I have is I am on well water, though *** never had it proffesionally tested, the test strips all indicate high PH and my other tanks do well with weekly 30-50% water changes and adding some aquarium salt and water conditioner for the chloramines. Will this be okay for the African Cichlid tank as well? The fish I am looking at getting so far are Blue Dolphins,Yellow Labs and Dogtooth. If anyone has any info or sugestions please feel free to comment!! Sorry this is so long I think Im on fish overload right now haha!!! Thanks in advance
