Yellow gourami (Trichopodus trichopterus) is a species native to Southeast Asia and
are famous as ornamental species. However, hobbyist and farmers encounter
problems where its body color easily becomes faded in captivity. Since color enhancer
pellet are expensive, an experiment was performed to determine whether tank color
can influence the body color intensity and growth of T. trichopterus. Four different
tank colors (white, yellow, blue and green) with five replicates were tested where fish
were kept under natural lighting (outdoor) conditions for two months. The result
demonstrated that fish reared in green colored tank showed an increment in its color
intensity while fish reared in white tanks increased its body weight. It can be concluded
that tank color does affects the body color intensity and weight of T. trichopterus. This
study will benefit farmers and hobbyist thus solving its color fading problem in a
cheaper way.
