General Description
The Randall's prawn-goby (Amblyeleotris randalli) belongs to the Gobiidae family, specifically Amblyeleotris. These fish are small, reaching a maximum size of 12.0cm, and are commonly known as Sailfin shrimpgoby, Gold-barred shrimp-goby, or Randall's prawn-goby. They are native to the Western Pacific, from the Moluccas to the Solomon Islands, north to the Ryukyu Islands, south to the northern Great Barrier Reef, and Palau in Micronesia.
Aquarium Suitability
Randall's prawn-goby is considered suitable for aquariums, particularly when kept in a symbiotic relationship with Pistol shrimps of the Alpheus genus. They require a minimum tank size of 100 liters and are hardy fish. However, they are known to be aggressive towards similar species, so care should be taken when selecting tank mates.
Demands, Care, and Hardiness
These fish are hardy in nature but need specific care requirements. They prefer a substrate that allows them to burrow, consisting of sand, coral pieces, shells, and broken pieces of shells. Providing suitable rock formations in the aquarium helps them to create secure holes. They are frequent feeders, requiring multiple feedings a day, especially when newly introduced.
Reef Suitability
Randall's prawn-goby is reef-safe and suitable for a reef aquarium environment.
Aquarium Setup
Setting up an aquarium for Randall's prawn-goby involves ensuring a suitable substrate for burrowing and providing adequate rock formations for hole creation. The tank should be well-structured with spaces for the fish to establish territories and feel secure. It is essential to keep the tank covered as these fish are known to jump out of open aquariums.
Behaviour
These prawn-gobies exhibit territorial behavior and can be aggressive towards most approaching fishes due to their innate nature of establishing their own territories.
Feeding and Diet
Their recommended diet includes small crustaceans like krill, mysis, and artemia. When natural food sources are scarce in the aquarium, it is crucial to feed them frequently to ensure their health and well-being.
Dimorphism and Captive Reproduction
There is no information available on dimorphism or captive reproduction for Randall's prawn-goby.
Habitat and Distribution
In the wild, Randall's prawn-gobies are found in the waters of Australia, Indonesia, and the Central/West Pacific region. They inhabit areas from the Moluccas to the Solomon Islands, with their range extending north to the Ryukyu Islands and south to the northern Great Barrier Reef and Palau in Micronesia.
