| Abstract | ||||
| Betta fish (Betta sp.) is one of the highly popular ornamental fish, with their market value and desirability significantly influenced by the brightness of their coloration and their survival rate. One way to increase the brightness and survival rate of betta fish is to provide natural feed containing carotenoids. This study aims to investigate the effect of various natural feeds on the color brightness of betta fish. The method used in this study was an experimental design with complete randomization, consisting of 4 treatments and 5 replications. The feed used for incomparison of this study was the type often used by betta fish breeders: (A) commercial pellets, (B) silkworms (Tubifex sp.), (C) bloodworms (Chironomus sp.), and water fleas (Moina sp.). Overall, the research confirmed that natural feeds significantly improve betta fish color brightness compared to commercial feed. This study showed that the group given water fleas had the fastest and most striking colors in weeks 2 to 6, with the brightness value decreasing from 79±2.2° in the first week to 29±2.9° in the sixth week. However, in the seventh week, silkworms had a better contribution than the other treatment with a final degree value of 19±3.8°. Regarding survival rates, there was no significant difference among the natural feed groups, with the commercial pellet treatment showing the lowest survival. Bloodworms as natural feed for betta fish are recommended to increase the brightness of the color (19±3.8°) and survival rate (93±15%) of the betta fish. Unfortunately, the exact carotenoid content of each natural food was not measured in this study. Further research is needed to isolate carotenoids from their sources and test them on betta fish to evaluate the color and other growth parameters. | ||||
