The fish, up close
The Tiger Oscar, scientifically known as Astronotus ocellatus, is a popular freshwater fish known for its striking colours and distinctive patterns. This species typically has a dark-coloured body with vibrant orange, red, and black markings, resembling a tiger's stripes. They have a robust build with a large head and sharp eyes. Oscars are intelligent fish and can recognise their owners. They are also territorial and can be aggressive towards tank mates, especially during breeding or if they feel threatened.
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
Oscars are known for their curious and interactive behaviour. They are active swimmers and enjoy exploring their environment. While they can be aggressive, especially during feeding or breeding, Oscars can also display social behaviours towards their owners. They may even learn to recognise their caretakers and interact with them during feeding times.
Tank planning
It is essential to provide ample hiding spots and decorations in the tank to help reduce aggression and provide security for the Tiger Oscar. Regular water changes and maintenance are crucial as Oscars are sensitive to poor water quality. Ensure the tank has a powerful filtration system to keep the water clean and well-oxygenated.

Tiger Oscar is listed with this tank recommendation: A single Tiger Oscar requires a minimum tank size of at least 200 litres to provide ample swimming space and territory. However, a larger tank, such as a 300-400 litre aquarium, is recommended to accommodate their size and aggressive nature. Tank mates should be chosen carefully, considering the Oscar's territorial behaviour. Ask in-store for advice based on your exact setup and tank mates.
