Abstract
Ornamental fish is a fishery commodity that has promising business opportunities. Ornamental fish will have a high selling value if they have bright and brilliant colors. The advantage of ornamental fish is in the intensity of the color on its body. This study aims to analyze the levels of Spirulina added in feed which can increase the color intensity of the Angelfish juvenille. The method used was an experimental method Completely Randomized Design, consisting of five treatments and four replications. The parameter observed was an increase in color on the head of the fish and analyzed using Kruskal-Wallis.The results showed that giving 3% spirulina flour in commercial feed could provide the best color improvement for angelfish with an increase in color value by 3, and if discontinued addition of spirulina flour can reduce the brightness level of the angelfish.
