24–28°C · pH 6–7.5 · 450L

Red Oscar is a bold South American cichlid for large, mature aquariums. Expect strong colour, real personality, heavy feeding and a need for careful tank-mate choices.
Adult size is the maximum length this species reaches at full maturity (scientific sources). The livestock you receive will be younger and smaller — pick a size variant above for the actual shipping size. Photos are AI-enhanced, so the animal may show subtle colour or marking differences.

Maintain these water conditions for optimal health and vibrant colors
Red Oscar (Astronotus ocellatus) is a large South American cichlid for keepers who want a confident centrepiece fish with real presence. This red form is valued for its orange-red patterning, heavy body shape and famously interactive behaviour. It is not a small community fish; plan the aquarium around the Oscar first.

Use a mature aquarium with strong filtration, open swimming space and robust decor that cannot trap or injure the fish. Oscars dig, push objects and produce a heavy bioload, so steady maintenance matters as much as tank size. Avoid small fish, delicate tank mates and cramped mixed-cichlid setups.
Feed a varied omnivorous diet built around quality cichlid pellets. Rotate in earthworms, prawns, mussel, crickets and suitable frozen foods. Avoid feeder fish; they add disease risk and do not make a balanced staple diet.
