The most diverse aquarium fish family — brilliant, brainy, and belligerent. Tank mates are a chess game.
Quick answer: Oscar is a variety of cichlids. Everything on this page is cichlids-level guidance — we do not invent variety-specific numbers.
The care below is cichlids-level guidance from our species hub, sourced to Merck Veterinary Manual — Aquarium and Pond Fish and RSPCA — Fish care. It applies to Oscar exactly as it applies to every other cichlids variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
Water chemistry by origin
This is the non-negotiable: African rift-lake cichlids need hard, alkaline water (pH 7.8–8.6); most South American cichlids want soft, slightly acidic (pH 6.0–7.0). Matching origin chemistry prevents chronic stress and disease. Test weekly with a liquid kit — strip tests lie. Frequent small water changes (30–50% weekly) keep nitrates low.
Diet and breeding chaos
Feed species-appropriate pellets plus frozen foods; Africans are largely herbivorous (algae-based), Americans are omnivorous/carnivorous. Overfeeding is the top water-quality killer — feed what is gone in 30 seconds, once or twice daily. Cichlids are mouth-brooders and cave-spawners; breeding pairs get violently territorial, so plan tank dividers or separate tanks.
