Care basics

Cichla ocellaris is a huge predatory cichlid and a famous game fish. Juveniles are sometimes sold in stores, but adults outgrow almost every home aquarium.

Only consider one if you can house a fish of more than two feet. It needs tank mates that are just as large, such as big catfish or arowana.
