| Abstract | ||
| This study aimed to evaluate the growth and color quality of the boesemani rainbowfish exposed to different light spectra. The boesemani rainbowfish, with an average weight of 1.46± 0.23g and length of 4.67± 0.25cm, were reared in an aquarium (33×50×40cm) for 60 days. The fish were fed commercial floating pellets twice a day till satiation. The study involved five treatments with three replications: treatment C (control), W (white LED), R (red LED), G (green LED), and B (blue LED). The results showed that exposure to blue LED light produced the best growth outcomes. The daily growth rate was 0.65± 0.12%, the absolute weight gain was 0.01±0.002g/ head/ day, and feed efficiency was 32.68± 10.59%. Red LED exposure resulted in the best color quality, with visual color performance measured at 51.32± 1.10% for blue, 51.58± 0.97% for orange, and 461±11 chromatophores per fish. Glucose levels ranged from 72.42± 29.60 to 99.13± 5.68mg/ dL. Fish stamina, measured by their ability to swim against the current, ranged from 61.26± 38.74% to 82.33± 17.67%. | ||
