Difference in Color Sensitivity of Poecilia reticulata raised in different light environments

Abstract – Poecilia reticulata has been a very common species of fish to investigate their vision and how they are able to sense color, which became an influence to this paper. From the experiment of raising them in two different groups, the question to how different environments of light can change sensitivity to color will be explored, based on data interpretations using the chi-squared method. Two schools of fish were put in two different light environments, one being orange and the other being green. The experiment made it possible to explore how little differences in the environment can hugely influence vision, as the results were able to prove that color can be an influencing factor on the sensitivity to color, where the fish raised under orange light was more sensitive to color compared to the other school of fish raised under green light.
