Equetus acuminatus | L

Equetus acuminatus, commonly known as the Jack-knifefish or Longfin Spadefish, is a visually distinctive marine grunt prized by experienced hobbyists. This large variant displays elongated dorsal fins and striking black and white banding, making it a standout addition to mature marine aquariums.

Care Level: Moderate to advanced care is recommended due to its specific dietary needs and sensitivity to water quality.

Temperament and Compatibility: Generally peaceful but can be territorial with conspecifics or similar species. Best kept singly or as a mated pair in a suitably sized tank. Compatible with other semi-aggressive or peaceful marine fish but avoid very small or slow-moving species that may be stressed.

Diet: Carnivorous; thrives on a varied diet including meaty foods such as mysis shrimp, brine shrimp, finely chopped seafood, and high-quality frozen or prepared marine fish foods.

Minimum Tank Size: A minimum of 180 litres (approximately 50 gallons) is recommended to provide ample swimming space and maintain stable water parameters.

Lighting and Water Flow: Standard marine aquarium lighting is sufficient. Moderate water flow mimicking natural reef currents is ideal to keep the fish active and healthy.

Placement: Provide plenty of open swimming areas combined with rockwork or caves for shelter. Ensure the tank is well-established with stable water conditions.

Origin: Not Provided.

Maximum Size: Up to 25 cm (10 inches) in length.

Reef Safety: With Caution. While generally reef safe, they may nip at small invertebrates or delicate coral polyps, so caution is advised in reef setups.
