Species description
Geographical Origin and Habitat: Western Tropical Pacific: from Ryukyu Islands to Micronesia and Samoa. Inhabits live Acropora colonies in shallow reef lagoons.
Taxonomy and Morphology: Member of the family Gobiidae. Deep, scaleless body covered with slippery skin. Reaches a maximum length of 4.5 cm.
Social Behavior: Sedentary and coral-dwelling. Lives in pairs and is territorial towards other Gobiodon. Extremely peaceful with other genera.
Coloration and Sexual Dimorphism: Body is uniformly golden-brown or light brown without markings or spots. No distinct sexual dimorphism.
Care, breeding and tankmates
Aquarium Setup: Suitable for nano reef aquariums of at least 40 liters. Housed best with live branching Acropora corals.
Diet and Feeding: Carnivorous. Feeds on zooplankton. Provide fine foods like cyclops, copepods, and rotifers three times daily.
Water Quality: Maintain stable marine parameters: temperature 24-28 °C, pH 8.1-8.4, salinity SG 1.020-1.025. Standard reef filtration.
Compatibility and Cohabitation: Peaceful with other tankmates. Do not house with large predatory fish. May nip host coral tissue to lay eggs.
Aquarium Breeding: Bidirectional hermaphrodite. Monogamous pairs lay eggs on host coral branches. Captive breeding is difficult due to larval size.
Risks and Diseases: Starvation in newly set up tanks. High resistance to skin parasites due to its thick, toxic mucus coat.
