Yellow Watchman Goby – Grey Morph
Cryptocentrus cinctus – The captive bred Yellow Watchman Goby is a beautiful goby that naturally varies in color. 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 often witness their gobies changing color in their tanks.
Watchman Gobies are well-behaved reef inhabitants that will not pick at coral, sessile invertebrates, or other species of fish. Avoid keeping it with aggressive species or animals that are large enough to eat small fish. Like other gobies, these can easily jump out.

The goby arrived healthy and active. It has been in my tank for two months and has shown a nice grey color with subtle blue dots. I feed it mysid shrimp and a bit of spirulina, and it seems to enjoy the diet. It’s very calm and doesn’t bother other fish or corals.
Dan Ross –
I was worried about compatibility with my reef tank, but this goby is very peaceful. It’s stayed in one spot and hasn’t shown any signs of aggression. The color is a bit muted, but I think it will brighten up with proper diet.
Edward Allan –
Great addition to my tank. It’s small, quiet, and doesn’t cause any stress to the other inhabitants. I’ve noticed it changes color slightly after a few weeks, especially when I add more carotenoid-rich foods.
