To date, the Mandarinfish is one of only two animal species known to have blue coloring because of cellular pigment. The name “cyanophore” was proposed for the blue chromatophores, or pigment-containing and light-reflecting cells.
Even though they are quite common in the aquarium trade, these fish are quite difficult to keep because of their specific diet. In the wild, they are restricted to eating live copepods and amphipods and some never get over these tasty requirements.
