Smallmouth Jack Aquarium Care Guide

Keeping Smallmouth Jack in an aquarium requires the right conditions.

Aquarium Information

• Care level: expert
• Temperament: aggressive
• Diet: carnivore
• Minimum tank size: 1000 gallons (3785 liters)
• Compatibility: Not suitable for typical community aquariums. Can be kept with other large, aggressive fish of similar size, but often best kept alone or in very large species-specific displays due to its predatory nature and rapid growth.
• Special requirements: Requires an extremely large aquarium with powerful filtration and strong water movement. A diet of high-quality, varied marine proteins (fish fillets, squid, shrimp) is essential. Due to its size and predatory behavior, it is rarely kept in home aquariums and is more suited for public aquaria.
