Originating in the waters of the Amazon, the Oscar fish is another extremely popular tropical fish. Their popularity stems from their personality, which has been compared to that of a puppy. Many keepers experience begging around meal times or the seemingly playful greetings they receive from their fish when they get home.
There are a few color varieties including albino, olive-green, brown and dark gray. They can get quite large, usually 12-14 inches and should be kept in a 55 gallon or larger aquarium. The Oscar is also known for being one of the more messy tropical fish to keep. Try to get the best filtration system possible for them and be prepared to perform frequent water changes. They are known to rearrange their environment from time to time and to bash in to filter uptake tubes and heaters. If you are wanting to keep live plants in an aquarium you may not want to get an Oscar because they love to dig up plants. They are also very good jumpers, so a heavy hood is a necessity.
