4 Discussion
In fishes, the xanthophores that showed the golden color are called the xanthophores. Changing in the density of
these chromatophores, the color of the fish body can be changed accordingly. The presence of the melanic
chromatophores usually masks the appearance of the xanthophores, but with the complete disappearance of the
former from any region of the fish body, xanthophores became revealed (Webber et al., 1973) and the case known
as xanthochromism. In such condition, the chromatophores contain E-carotene and canthaxanthin and import a
golden colour (Webber et al., 1973). It has been suggested that xanthophores may even be over-produced in the
absence of melanophores or other pigment cells (Angus and Blanchard, 1991).
