Caring For Your Oscar Fishes
Oscar Fishes grow fast. One of the cichlid fish, a juvenile Oscar can grow more than an inch (2.5cm) per month, so it will rapidly outgrow a starter aquarium. However, if you want a very large aquarium, this is an excellent fish to keep in it.
The key to a healthy, happy Oscar is aquarium stability and a varied diet. This fish doesnt really care exactly what pH, hardness, or temperature its water is, but it needs whatever the levels are to stay that way, not fluctuate every time fresh water is added to the tank. Many people make the mistake of only feeding pellet food or feeder fish, but Oscars require different kinds of food to get all the nutrition they need.
Keeping an Oscars tank clean can be difficult, especially if the aquarium is only the minimum size. These fish put out a huge amount of waste every day. A strong filtration system is an absolute must, as are regular water changes. Also, be careful about what kind of decorations are used in an Oscars aquarium. These fish are not nimble, so they swim into things. They also like to move things around. Driftwood and smooth rocks wont scrape Oscars if they bump them, so these are good options for tank furniture.
Oscars Fishes are aggressive if too many Oscar fishes are crowded in small aquarium, or if they are breeding.
