Tiger Oscar

Astronotus ocellatus

The Tiger Oscar is the most popular colour variant of Astronotus ocellatus — a large, intelligent South American cichlid prized for its bold orange-and-black patterning, interactive personality, and impressive size. Capable of reaching 35 cm (14 in) in captivity, Tiger Oscars demand spacious tanks, powerful filtration, and a keeper who appreciates a fish with genuine character. This guide covers every aspect of Tiger Oscar husbandry — from tank dimensions and water chemistry to feeding protocols, breeding, and common health issues.

Albino Oscar

Astronotus ocellatus

The Albino Oscar is a leucistic colour morph of Astronotus ocellatus that replaces the species' typical dark pigmentation with a striking white or cream base highlighted by vivid red-orange markings. Pink eyes confirm the absence of melanin. While care requirements mirror those of standard Oscars, albino specimens have specific light-sensitivity considerations and can be slightly more susceptible to stress in brightly lit environments. This guide covers everything specific to Albino Oscar care, with reference to our Tiger Oscar guide for shared husbandry fundamentals.
