YELLOW WATCHMAN GOBY GREY MORPH BIOTA

Cryptocentrus cinctus - The captive bred Yellow Watchman Goby is a beautiful goby that naturally varies in color. This is the grey morph. Both in the wild and in captivity, this species can be mustard, pale with olive-grey bands, or bright yellow, all with iridescent blue dots. Feeding a diet heavy in astaxanthin and carotenoids can help them to retain their bright coloration. Gobies on lighter colored substrates also tend to be brighter over time. Hobbyists even sometimes witness their gobies changing color in their tanks. Having one of each color would make an interesting display in a home tank.
