Care

Ward's Sleeper Goby requires an aquarium with a sandy bottom where it can perform its natural sifting behavior. They are generally hardy but can be sensitive to poor water quality, so regular water changes and a well-maintained filtration system are essential. They are not aggressive towards other tank mates and can be kept with a variety of fish and invertebrates.

Reproduction

In the home aquarium, breeding Ward's Sleeper Goby can be a challenge. They are not commonly bred in captivity, and little is known about their breeding habits in the wild. However, they are thought to form monogamous pairs and lay eggs in burrows.

Habitat

Ward's Sleeper Goby is found in the Indo-Pacific region, from the Red Sea to Samoa, and north to the Ryukyu Islands. They typically inhabit sandy and rubble substrates in lagoons and coastal reefs, often at depths of 1 to 30 meters.
