Abstract This study explored the combined influence of tank color, stocking density, and gender on Tilapia zillii 's performance well‐being. In this 120‐day trial, 320 T. , each initially weighing 10.0 ± 0.1 g/fish, were distributed among 24 tanks. The experiment included eight distinct treatment combinations, varying color (blue green), density (10 30 fish/m 3 ) sex (monosexual mixed). results showed that blue tanks improved specific growth rate condition factor, while green better for feed utilization. Density at highest mean values final body weight total length, gain (WG), length. Mono‐sex outperformed mixed‐sex ones in WG daily growth.
