General information

Randall's Shrimp Goby, scientifically known as Amblyeleotris randalli, is a small, colorful fish that is popular among saltwater aquarium enthusiasts. This species is known for its symbiotic relationship with pistol shrimps, which makes it a fascinating addition to a reef tank. The goby's body is elongated with a pattern of orange to red lines against a pale background, and it can reach up to 10 centimeters in length.

Care

Randall's Shrimp Goby requires a tank with a sandy substrate to allow for burrowing, which is essential for their well-being. They are generally peaceful and can be kept with other non-aggressive tank mates. Stable water conditions and a varied diet of meaty foods are important for maintaining their health.

Reproduction

In the aquarium, breeding Randall's Shrimp Goby can be challenging. They are known to spawn in captivity, but raising the larvae requires a separate rearing tank with appropriate food and conditions.

Symbiosis

The most notable behavior of Randall's Shrimp Goby is its symbiotic relationship with alpheid shrimps, commonly known as pistol shrimps. The shrimp maintains and digs a shared burrow while the goby acts as a lookout for predators. This mutualistic relationship provides the shrimp with protection while the goby gains a safe haven.

Habitat

Randall's Shrimp Goby is found in the Western Pacific, from the Ryukyu Islands to Australia. They inhabit sandy areas near reefs, often sharing burrows with pistol shrimps at depths of 5 to 35 meters.
