How To Care for Oscar Fish

Oscar fish are one of the few predatory fish preferred by aquarium aficionados. While caring for Oscar fish is relatively easier as compared to other species of fish, they can be prone to diseases if not maintained in a suitable environment.

1. Ready the fish tank.  Oscar fish can grow up to two feet in length so a correct size of aquarium is necessary. For every Oscar fish, a 40 gallon tank has to be provided. A heater has to be installed to regulate the water's temperature between 74 and 81 degrees Fahrenheit. Bear in mind that incorrect temperature levels can severely damage your Oscar's health so having a thermometer will be a worthy investment. Water filters are very crucial when caring for Oscar fish because they are voracious eaters hence they produce more wastes. Oscar fish can exhibit highly aggressive behavior especially if there are other fish in the tank. To reduce stress, have a bunch of aquatic plants that will serve as hiding places. Oscars tend to rearrange aquarium decorations as well. So unless you do not mind having them rearranged according to your Oscar's aesthetic sense, it might be a good idea to choose those that are heavy but free of any sharp edges.
2. Maintain the aquarium.  Perform up to 20% water changes every week to make sure that the water isn't toxic for your Oscar. While filters clean the water, not everything is processed. Water changes assist in keeping the toxicity levels from harming your Oscar fish. You may also consider setting up several smaller filters in the aquarium. Just make sure the water pressure does not disrupt your Oscar.
3. Feed your Oscar fish. Oscars are predatory fish and as such are predominantly meat eaters. Provide it with an assortment of protein-rich processed, freeze dried or frozen fish food. Keep in mind to feed your Oscar fish only once a day. Feeding it more often will mean that they will produce more waste. If this is the case, frequent changing of water is imperative. After feeding, remove any leftover fish food from the tank as this will contribute to poor quality of water in the aquarium.

Oscars are predator fish. If you decide on adding some other types of fish as its companion in the tank, it would be best to choose those that are at least equal to the Oscar's size to avoid having it mistaken for food.
