Orectolobus japonicus, commonly known as the Japanese Wobbegong, is a unique and fascinating carpet shark species prized by advanced marine aquarium hobbyists. Known for its intricate patterning and flattened body, this shark is a bottom-dwelling predator that requires specific husbandry conditions to thrive in captivity.
Care Level: This species is recommended for experienced keepers due to its specialised dietary and environmental needs.
Temperament and Compatibility: Generally sedentary and nocturnal, Orectolobus japonicus is a relatively peaceful shark but can be predatory towards smaller tankmates. It is best housed with larger, robust fish that are not small enough to be considered prey. Avoid keeping with small or slow-moving species.
Diet: Carnivorous, feeding primarily on meaty foods such as fish, crustaceans, and cephalopods. Regular feeding with fresh or frozen seafood is essential to maintain health.
Tank Requirements: Due to their size and behaviour, a minimum tank size of 600 litres is recommended, with a large footprint and plenty of hiding places such as caves and rockwork. A sandy substrate is preferred to mimic their natural environment.
Water Parameters: Stable marine conditions with temperature between 22-26°C, salinity around 1.025 SG, and good water quality are essential. Moderate water flow is suitable to replicate their natural habitat.
Reef Compatibility: No. This species is not reef safe as it may prey on invertebrates and smaller fish.
Origin: Native to the coastal waters of Japan and surrounding regions.
Maximum Size: Can reach up to 1.2 metres in length in captivity.
