I'm stocking a 55g standard tank. I currently have 5 platies and 5 otos. I want to add an Angelfish, a pair of Bolivian Rams and a schooling fish (which I can't decide between Bleeding Hearts and Lemon Tetras). I know that all of the fish are compatible, however, does anyone have a suggestion on the order in which the fish should be introduced? For example, should the Angel be put in next? The rams? Schooling fish? I can find water parameters and compatibility information through research, but there is no information on what fish should go in the tank before or after others. Any and all help is appreciated.
