Watchman Goby

Description

Cryptocentrus cinctus

The captive-bred Yellow Watchman Goby is a beautiful goby that naturally varies in colour a bit. They 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-coloured substrates also tend to be brighter over time.

Yellow 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 of an aquarium when chased or frightened, so a tight-fitting lid is required. With a max size of 4" they require an aquarium of at least 30 gallons. Though they are peaceful fish, they will use their large mouths to display or push other fish away from their burrows. They are territorial toward other shrimp gobies, so be sure to give each goby adequate room for territory if you're keeping more than one shrimp goby. We recommend using an acclimation box to introduce new fish to your aquarium.

Acclimation

Temperature Match

Place the sealed bag containing the fish or invertebrate into your tank. Allow it to float for 15-20 minutes to gradually equalize the temperature between the bag and your aquarium. This step minimizes stress caused by sudden temperature changes.

Drip Acclimation

Set up a drip acclimation system by using airline tubing. Start a slow siphon from your tank into the bag or bucket containing the fish or invertebrate, allowing water to drip slowly. Acclimate over a period of approximately 30 minutes, gradually increasing the volume of tank water to match salinity and other water parameters.

Check Salinity

Use a refractometer to measure the salinity in the bag or acclimation container. Ensure the salinity matches your tank’s salinity before transferring the fish or invertebrate. Matching salinity helps reduce stress and prevents shock when introducing new animals.

Release Fish/Invert

Gently transfer the fish or invertebrate into the tank, avoiding netting them if possible to reduce physical stress. Allow the animal to swim out on its own if transferring from a container. Discard the acclimation water, as it may contain contaminants.
