Hello, i have a 9 inch red headed cichlid i just recently acquired from a lfs, not sure if its male or female yet, they dorsal and anal fin are quite rounded off so i assume female, anyways i currently have the red head in a 120 gallon with an 11inch oscar(big wimp) and a 4.5 inch flowerhorn( pretty mild tempered), wondering if i could anything else to the tank?
