How To Pick The Best Oscar Fish Aquarium?

Oscar fish is known as very difficult to care for, but not because it is aggressive or needs special treatment, but because it needs a lot of space to live. It isn’t just about the space, so we bring you additional tips on what to check before choosing the aquarium.

Aquarium Size – The oscar fish has very strict directions for tank size – it needs to be bigger than 30 gallons and the bigger it is, the better for the fish. You can place them temporarily in smaller models, but they grow quickly, from 1 to 4 inches per year, and will need quick transport to a bigger tank.

Additional Equipment – Those fish are freshwater and need less care than saltwater, but you need to provide them good care to survive. First, you will need a regular 3-way filtration system and light to ensure it is enough even during the night. What is more, those are tropical fish and need warmer water, so you might need to install a water heater to keep it around 20°C.

Decoration And Environment – In the big oscar fish tanks, there are plenty of ideas on how to decorate the environment to make it more appropriate for an oscar fish. Be sure to use natural elements and colors, like branches, grass… If you have a smaller tank, use one statement decoration, like a big rock in the middle. They must have enough space to swim.

Cleaning And Maintaining – Oscar fish consume a lot of food and leave a lot of loads behind, so you need to have a good filtration system. If you don’t use filtration, you need to clean it regularly, at least once a week to keep it clean.

Ideal Aquarium Type – There is no ideal aquarium type you can use for keeping an oscar fish. Yet, bigger aquariums, like wall and floor models, are better for more swimming space. Don’t choose weirdly shaped models, instead stick with a cube and basic design.
