Oscar Cichlids (Astronotus ocellatus) are captivating and intelligent tropical aquarium fish known for their vibrant colors and distinctive personalities. To ensure their well-being, house them in a spacious tank of at least 75 gallons, as Oscars can grow up to 12-14 inches in length. Maintain water temperatures between 74-81°F (23-27°C) and a pH level of 6.5-7.5. A powerful filtration system and regular water changes are crucial, as Oscars produce a lot of waste.
Offer a varied diet of high-quality pellets, live or frozen foods, and occasional vegetables. Oscars are territorial and may be aggressive, so select tankmates carefully. With diligent care, Oscars can become friendly and engaging additions to your tropical aquarium, showcasing their unique behaviours and personalities.
