Instructions

      Keep your tank the correct temperature. Your tank should remain between 75 and 80 degrees Fahrenheit. Getting your tank anywhere above 80 degrees can be very harmful to your Oscar, so be sure to buy both a heater and a thermometer.

      Buy the correct amount of aquarium space. Oscars can grow to sixteen inches which is a huge fish for a home aquarium. Be sure to have at least 40 gallons of water per every Oscar that you have in your aquarium.

      Keep your tank clean. You need to replace at least 20 percent of your tank water every week to keep you tank clean. Unfortunately the Oscar fish is quite the defecator, so you may also want to invest in a few tank cleaner fish to help with your tank cleaning duties.

      Feed your Oscars correctly. Oscars seem to love blood worms. If you keep your fish well fed it will also be less likely to attack and bite at any other cichlids you have in your tank. As long as provide your Oscar with a high protein diet, they will grow just fine.

      Manage with other fish in your tank. Oscars are a cichlid. This means that they are an aggressive and territorial fish. They do get along with some other types of cichlids, but they will need to be raised together in the same tank, or moved into a new tank together where neither has claimed a territory. Remember that for every fish you need to recalculate the tank size needed. You can also invest in bottom dwellers and eels without too much worry about your Oscar beating them up.
