Oscar Aquarium Care Guide

Keeping Oscar in an aquarium requires the right conditions.

Aquarium Information

• Care level: intermediate
• Temperament: aggressive
• Diet: carnivore
• Minimum tank size: 75 gallons (280 liters) for a single adult, larger for multiple or growing fish
• Compatibility: Best kept alone or with other large, robust cichlids or similarly sized, semi-aggressive fish that can withstand its territorial nature. Avoid small or docile tank mates.
• Special requirements: Requires a spacious tank with strong filtration due to its messy eating habits and large waste production. Provide plenty of hiding spots using large rocks, driftwood, and sturdy artificial plants. Oscars are known to rearrange tank decor, so ensure items are stable. A varied diet of high-quality pellets, frozen foods (shrimp, krill), and occasional live foods is essential. They are sensitive to poor water quality.
