The invention provides a feed additive for cichlasoma citrinellum XC.synspilum, with carotenoid. The feed additive is specially prepared from the following components in percentage by mass: 1%-5% of carotenoid, 1%-6% of phospholipid, 1%-5% of vitamin, and 2-5% of a green bamboo extract. The additive disclosed by the invention consists of the carotenoid, the phospholipid, the vitamin and the green bamboo extract, wherein the green bamboo extract can effectively promote the cichlasoma citrinellum XC.synspilum to absorb the carotenoid, the phospholipid and the vitamin, so that the best effects of color enhancement, oxidation resistance and the like of the cichlasoma citrinellum XC. synspilum can be achieved. According to the feed additive disclosed by the invention, the carotenoid and the phospholipid are mixed in the ratio of the carotenoid to the phospholipid being 1 to 1, so that the best coloring effect of the cichlasoma citrinellum XC. synspilum is achieved, and coloring of the cichlasoma citrinellum XC.synspilum is facilitated; the carotenoid and vitamin E are mixed in the ratio of the carotenoid to the vitamin E being 1 to 3, so that improvement of the oxidation resistance of the cichlasoma citrinellum XC.synspilum is facilitated; and the carotenoid and the phospholipid are mixed in the ratio of the carotenoid to the phospholipid being 1 to 3, so that the improvement of the liver function of the cichlasoma citrinellum XC.synspilum are facilitated.
