Abstract/Summary

Six 3-month old female Betta splendens or fighting fish were exposed to different light rays of yellow, orange, red, green, and blue and placed individually in six 1000 ml beakers wrapped with one layer of cellophane of the respective colors. A sixth beaker was left unwrapped to serve as the control specimen. Physical conditions such as temperature, pH, food distribution and water level were monitored and kept constant. Initial and final data on color and length in size were taken. After the experimental period of one month, results revealed that the fish in the yellow beaker developed darker pigmentation and grew the longest while those in the green and blue beakers paled in the color and had minimum growth. Fishes in the red and orange beakers had intermediate results. The effects of background color and illumination were the factors considered in this study.
