Hello Alan With a pH of around 7.5 ..... I would suggest you pick some fish that come out of Peru... water there tends to be higher pH then that coming out of Brazil.... I would suggest you start off with Apistogramma Cacatuoides.... Maybe Bitaeniata....Aggies.... Starting with these guys should get you off and running.... Cacatuoides would be my first pick. Good luck with your endevors..... keep us informed how you're doing and dont forget to ask questions when they arise....
