Description
The Rough-finned Oscar (Astronotus crassipinnis) is a large, robust South American cichlid found in the Amazon basin. Closely related to the more common Oscar, it typically exhibits a darker, more uniform coloration and may lack the distinct caudal ocellus. These intelligent fish require a spacious aquarium and are known for their strong personalities.
