Keeping Green Pufferfish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: advanced
  • Temperament: aggressive
  • Diet: carnivore
  • Minimum tank size: 30 gallons for a single juvenile, 50+ gallons for an adult
  • Compatibility: Species-only tank recommended due to their aggressive and fin-nipping nature. Can be kept in groups of 3+ in very large, appropriately set up brackish tanks, but aggression can still be an issue.
  • Special requirements: Requires brackish water, with salinity gradually increasing as the fish matures. Excellent filtration is essential due to their messy eating habits. A varied diet of hard-shelled invertebrates is crucial for dental health. Plenty of hiding spots and visual barriers are needed to reduce aggression.
