The most effective and dominant type of carotenoids for coloring fish is carotenoids derived from carrot flour because it is a natural source of beta carotene which can improve the quality and color brightness of ornamental fish such as lemon fish. The research design used a completely randomized design (CRD) with four treatments (carrot flour 0%, 5%, 10% and 15%) and three replications. The feed was tested on lemon cichlid fish measuring 3.7 - 4 cm and weighing 0.8 - 1 g which were kept in a 10 L jar. Parameters observed were growth rate, absolute weight, absolute length growth rate, survival rate, water quality and color increase in lemon fish. The results showed that the addition of 15% carrot flour had an effect on the color 9% brightness of lemon fish (Labidochromis caeruleus). The results showed that the addition of carrot flour for growth and color improvement was in the 15% carrot flour treatment, the absolute weight growth value was 0.73 g/fish, length 0.56 cm/fish, survival rate was 96.6%. The addition of carrot flour to the growth and color improvement can be concluded that a dose of 15% affects growth and can increase the color of lemon fish.]]>
