Tiger Goby fish (Valenciennea wardii), is also known as the Ward's Sleeper, Tiger Watchman Goby, or Tiger Sleeper Goby, is a beautiful saltwater fish that belongs to the Gobiidae family. They are also known as Wardi Goby or Yellow Watchman Goby due to their vibrant colors and unique behavior. Proper care is crucial to keep these fish healthy and happy in an aquarium setting.

Tank Size and Environment

Tiger Goby fish can grow up to 4 inches in length and require a tank size of at least 30 gallons. They need a sandy substrate and plenty of hiding places, such as caves or live rocks. It's essential to provide them with enough space to swim and burrow, as they are known for digging tunnels in the sand. A well-established aquarium with live rock can help create a suitable environment that mimics their natural habitat.

These fish are generally peaceful and can be kept with other non-aggressive fish species. However, it's best to avoid keeping them with larger and aggressive fish that may bully them or compete for resources.


Tiger Goby fish are carnivorous and primarily feed on small crustaceans and worms. In a home aquarium, they can be fed a varied diet of live or frozen foods, such as brine shrimp, mysis shrimp, and bloodworms. It's important to avoid overfeeding as it can lead to poor water quality and health issues.

Behavior and Compatibility

Tiger Goby fish are relatively peaceful and can be kept in pairs or small groups with other non-aggressive fish species. They are known to form symbiotic relationships with pistol shrimp, which can also be added to the tank. These fish are also known for their unique behavior, where they pair up with a pistol shrimp and live together in the same burrow. The shrimp will maintain and clean the burrow, while the goby will keep watch for predators.

It's essential to provide plenty of hiding places and burrowing space, as these fish are burrowers by nature. They can become stressed if they do not have adequate space to dig and burrow. Therefore, it's crucial to avoid overcrowding the tank.

Health and Disease

Tiger Goby fish are generally hardy and not prone to diseases if provided with a suitable environment and a varied diet. However, they can be susceptible to common fish diseases, including bacterial, fungal, and parasitic infections.

It's essential to observe their behavior and look for any signs of illness, such as loss of appetite, lethargy, or abnormal swimming patterns. If any signs of illness are noticed, it's crucial to isolate the affected fish and treat them accordingly.

In conclusion, Tiger Goby fish are a beautiful and fascinating addition to any aquarium. They require a suitable environment, a varied diet, and proper care to thrive. Providing them with adequate hiding places and burrowing space and keeping the water quality in check can help keep them healthy and happy. Their unique behavior and symbiotic relationship with pistol shrimp make them an interesting and entertaining fish to observe.
