About the Diamond Watchman Goby
Diamond watchman gobies are active sand-sifting fish that scoop substrate and pass it through their gills while searching for food. This keeps them busy, but it can also bury low corals and move surprising amounts of sand.
They need direct feeding. A new, small or overly clean sand bed may not contain enough natural food to maintain body condition.
Health risks to know about
Starvation is a major concern, along with jumping injuries, ammonia or nitrite poisoning, marine parasites, bacterial disease and injury from unstable rockwork.
A pinched belly, rapid weight loss, rapid breathing, repeated scratching, sores or refusing prepared food needs prompt attention.
Tank, water and equipment
Use a mature, fully cycled marine aquarium with a secure lid, a broad bed of fine sand, stable rocks resting on the tank base and open bottom territory.
Measure salinity with a calibrated refractometer. Keep delicate corals off the sand and make sure digging cannot undermine the rock structure.
Food and feeding
Offer a complete sinking marine carnivore or omnivore food with suitable frozen marine foods. Natural sand fauna is helpful but not a complete plan.
Deliver food near the goby's territory and track body condition closely.
Behaviour, tank mates and enrichment
Repeated mouthfuls of sand, burrow maintenance and spreading sand around the aquarium are normal.
It is generally coral safe, but its digging can bury frags, rearrange the bottom and create conflict with other sand-dwelling fish.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
