|Common name||Oscar, Tiger oscar, Red tiger oscar, Velvet cichlid
|Scientific name||Astronotus ocellatus|
|Size||12" (30cm) or more.|
|Tank setup||A large tank (see below), with plenty of open space and robust decor. Ensure that heaters are protected from breakage.|
|Compatibility||Not for the community tank! Small fishes will be eaten. Robust tankmates should be chosen with care.
|Water chemistry||Not critical: around neutral pH (6.5-7.5), soft to fairly hard|
|Feeding||Carnivorous: live and dead meaty foods and pellet/tablet foods.|
|Sexing||No obvious differences. Pairs are usually obtained by allowing one to form naturally from a group of juveniles.|
|Breeding||A large number of eggs are laid on a pre-cleaned surface. The eggs and fry
are tended by both parents.|
The attractive colouration of juveniles makes them very popular, but this fish grows very large, and a single adult
is likely to require a tank of around 50 gallons minimum eventually. A pair will require a tank of around 80 gallons or larger.
They are enthusiastic and messy feeders, so a good filtration system is essential.
Oscars are considered one of the ultimate 'pet' fish, due to their obvious intelligence and personality - almost every long-term
oscar owner has a story to tell about the antics of their 'pet'!
