Gnathanodon speciosus | M

Gnathanodon speciosus, commonly known as the Golden Trevally, is a visually impressive member of the Carangidae family. This medium-sized marine fish is prized for its distinctive yellow and black striped pattern and dynamic swimming behaviour.

Care Level: Moderate to advanced. This species requires a well-established aquarium with ample swimming space and stable water conditions.

Temperament and Compatibility: Generally peaceful but active, Gnathanodon speciosus can coexist with other robust tankmates. Avoid housing with very small or timid species as it may outcompete them for food.

Diet: Carnivorous. Feed a varied diet including high-quality frozen or live meaty foods such as shrimp, squid, and small fish. Supplement with formulated marine pellets to ensure balanced nutrition.

Minimum Tank Size: A minimum of 300 litres (approximately 80 gallons) is recommended to accommodate its active swimming needs and growth potential.

Lighting and Water Flow: Standard marine aquarium lighting is sufficient. Moderate to strong water flow mimics its natural coastal and reef-associated habitats.

Placement: Provide open swimming areas with some rockwork or coral structures for shelter. Ensure the tank is securely covered as this species is known to be a strong jumper.

Origin: Indo-Pacific region.

Maximum Size: Up to 70 cm in the wild, but typically smaller in captivity.

Gnathanodon speciosus is a captivating addition for marine aquarists seeking a dynamic and visually striking fish. Proper care and tank conditions will ensure a healthy and long-lived specimen.
