Keeping Jacksmelt in an aquarium requires the right conditions.

Aquarium Information

  • Care level: expert
  • Temperament: peaceful
  • Diet: carnivore
  • Minimum tank size: 500 gallons
  • Compatibility: Best kept in species-specific tanks or with other large, peaceful, cold-water marine fish that can tolerate similar schooling behavior and water parameters. Avoid aggressive or territorial species.
  • Special requirements: Requires a very large, well-filtered, and highly oxygenated aquarium with strong water flow to simulate natural coastal environments. Schooling behavior necessitates a large group (minimum 6-8 individuals). Live food (e.g., brine shrimp, mysis shrimp, small feeder fish) is essential, and they are sensitive to poor water quality. Not typically suitable for home aquaria due to size and specific needs.
