The fish, up close
The Oscar cichlid, scientifically known as Astronotus ocellatus, is a popular freshwater fish prized for its vibrant colours and unique personality. They have a robust, oval-shaped body with distinct patterns and colour variations, including tiger-striped, albino, and red colour morphs. Oscars have a large mouth and sharp teeth, indicative of their carnivorous nature. They are intelligent and interactive fish, often recognising their owners and eagerly greeting them during feeding times.
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
Known for their bold and sometimes aggressive behaviour, Oscars can be territorial, especially during breeding or if housed with smaller tankmates. They are active swimmers and may rearrange decorations in the tank. Oscars are intelligent fish that can be trained to hand-feed and recognise their owners.
Tank planning
Maintaining water quality is crucial for the health of Oscars, as they are sensitive to poor water conditions. Regular water changes and efficient filtration are essential. Provide ample hiding spots and decorations to mimic their natural habitat. Keep an eye on their teeth growth, as they may require occasional trimming by a veterinarian.
