Abstract: This study on light and dark background color aimed to examine whether the background color could affect the growth performance of Nile tilapia fingerlings. Ninety (90) Nile tilapia fingerlings size-14 and nine aquaria were used in the study. The aquaria were covered with cellophane with white (treatment 1) and black (treatment 2) color and with no cellophane (as control). The fish were fed with pellet diets (30% crude protein) twice a day at 3% of their body weight, assessing their growth for four weeks. The results of the study showed that the aquaria with light background have the highest results in terms of weight gain (3.72g±2.59), average daily body weight gain (0.13g±0.09) and specific growth rate (3.11%±1.73) though statistical analysis showed no significance. The highest survival rate (33.33%) was observed in control, which is significant in treatment 2 and 3.
