Fifteen-spined stickleback Aquarium Care Guide

Keeping Fifteen-spined stickleback in an aquarium requires the right conditions.

Aquarium Information

• Care level: advanced
• Temperament: semi-aggressive
• Diet: carnivore
• Minimum tank size: 75 gallons (280 liters)
• Compatibility: Best kept in a species-specific tank or with other robust, non-aggressive marine species of similar size that can tolerate cooler water. Avoid small, delicate fish or those that might be prey.
• Special requirements: Requires a well-established marine aquarium with excellent filtration and stable water parameters. Abundant live rock and marine vegetation (e.g., seagrass, macroalgae) are crucial for providing shelter and mimicking its natural habitat. A strong current is beneficial. They are sensitive to poor water quality and high temperatures.
