Common name: Ornate Goby

General information

The Ornate Goby, scientifically known as Istigobius ornatus, is a small, colorful fish that is a popular choice for saltwater aquarium enthusiasts. This species is known for its distinctive diamond-shaped spots and peaceful demeanor, making it a charming addition to any reef or fish-only aquarium.

Care

Ornate Gobies are relatively easy to care for, but they do require a tank with a sandy substrate to mimic their natural environment. They are burrowers and will often create small caves under the sand to hide and sleep in. These gobies are not aggressive and can be kept with a variety of other peaceful fish and invertebrates.

Reproduction

In the wild, Ornate Gobies form monogamous pairs and lay their eggs in burrows. In the aquarium, breeding is less common, but with a well-established pair, spawning may occur. The male typically guards the eggs until they hatch.

Symbiosis

Ornate Gobies are known to engage in a fascinating symbiotic relationship with snapping shrimp of the genus Alpheus. The shrimp digs and maintains a burrow that both the goby and shrimp inhabit. The goby, with better eyesight, acts as a lookout for predators, while the shrimp provides a safe home.

Habitat

Istigobius ornatus is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, and from the Ryukyu Islands to the Great Barrier Reef and New Caledonia. They inhabit sandy areas and rubble patches of lagoons and seaward reefs, usually at depths of 1 to 30 meters.
