I am new to the hobby and recently acquired a 65G cichlid tank. It came with all supplies including fish. I fear that some compatibility issues may arise. Could use some expert opinions. Please keep in mind I did not choose to put these fish together they came with the tank. There are: 3 pseudotropheus socolofia (male, female, juvinal) 1 male Maylandia estherae (red zebra) a pair of Amatitlania nigrofasciata (convicts) 1 male Rocio octofasciata (Jack Dempsey) 1 Rafael spotted cat fish 2 Sterba corydoras 1 peacock eel There was a large and smaller Flowerhorn when I got it but I knew that was not a good idea so I took them out and traded them for 2 fish in a mixed peacock tank but I have done some research and think they are actually a pair of juvenile Maylandia lombardo (Kenyi). What should I change if anything?
