Keeping Rainbow Runner in an aquarium requires the right conditions.

Aquarium Information

• Care level: expert
• Temperament: semi-aggressive
• Diet: carnivore
• Minimum tank size: 2000 gallons (7570 liters)
• Compatibility: Due to its large size, active nature, and schooling behavior, it is only suitable for very large public aquariums or exceptionally large, specialized home aquariums with robust filtration and compatible large, fast-swimming species. Not suitable for typical home aquaria.
• Special requirements: Requires immense swimming space, strong water flow, and a diet of high-quality, varied marine proteins. Prone to stress in confined spaces. Schooling species, so multiple individuals are preferred, further increasing space requirements.
