A General Overview of the Oscar Fish - Astronotus ocellatus

OSCARPAIR2Scientific Name: Astronotus ocellatus (invalid/outdated synonyms: Lobotes ocellatus,  Cychla rubroocellata, Acara compressus, Acara hyposticta, Astronotus ocellatus zebra, and Astronotus orbiculatus)

Common Names: Oscar Fish, Velvet Cichlid, Marbled Cichlid, or any number of color/pattern variations + Oscar (Tiger Oscar, Red Oscar, Common Oscar, Albino Oscar, Lutino Oscar, Wild Type Oscar)

Size: 12-16 inches standard length (SL) and up to 3.5 pounds (though closer to 12+ inches SL is more typical in a home aquarium).  When young, can grow at the impressive rate of up to 1+ inches per month.  Don't be fooled by their small purchase size and get a small tank thinking you will have time to upgrade later; this is a common mistake.

Guide to initial Setup for an Oscar Fish Tank

For those of you who are thinking about buying an Oscar fish, or for those of you who have impulsively bought an Oscar fish, this article will go over some basic pointers about setting up an aquarium for your new friend. Oscars are a serious commitment due to their longevity and adult size. Having the correct set up will make their transition from little wriggler to a big brute as seamless as possible.

This article serves as an overview of the different aspects of owning Oscars. For additional details we also recommend reviewing the New Oscar Owner Information Packet.

Oscar Fish Tank Mates

Astronotus ocellatus is a great aquarium fish to keep. They can be very personable and full of character. Some even interact with their owners. The first myth I'd like to dis-spell is the myth that oscars get lonely. They do not get lonely. They are not a schooling fish, and do not desire to be surrounded by other fish. Even so, some of you will want to add to your tank and are eventually going to ponder that one question; what fish make the best Oscar fish tank mates? The answer is largely dependent upon a few things.

Oscar Fish Diet – What Do Oscar Fish Eat?

Let’s start with a premise. The object of feeding Oscars in captivity is to duplicate or simulate the fish’s diet in the wild. To provide them with nutrition that nature has designed the Oscar’s body chemistry to metabolize. One thing, I assure you, a wild Oscar swimming in a tributary of the Amazon River has never eaten is a goldfish. Do Oscar's eat fish? Sure, fish are a component of their diet in the wild. But goldfish are not.
