The fish, up close
The Chilli Red Oscar, scientifically known as Astronotus ocellatus, is a striking freshwater fish with a bold personality. Known for its vibrant red colouration, this species often displays black and orange patterns on its body, resembling a fiery appearance. Oscars have oval-shaped bodies with a protruding forehead and large eyes. They are powerful swimmers and can grow quite large, making them an impressive centrepiece in a well-decorated aquarium. Chilli Red Oscars are intelligent fish and can even recognise their owners, often begging for food when approached.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
These Oscars are known for their territorial and aggressive nature, especially towards smaller tank mates. They may exhibit fin nipping and dominance behaviours, so it's essential to house them with fish of similar size and temperament. Despite their aggression, Chilli Red Oscars can be very interactive and may even respond to their owners' presence.
Tank planning
Maintaining good water quality is crucial for Chilli Red Oscars. They prefer water temperatures between 24-28°C and slightly acidic to neutral pH levels. Regular water changes and a powerful filtration system are necessary to keep their environment clean. Provide ample hiding spots and decorations to create territories within the tank.
