Oscar fish typically cost around $10-$20 per fish. With that said, certain types of oscars with unique colorations can demand higher prices. Specialty oscar fish, such as albino oscars, can cost anywhere from $30 to several hundred dollars.
Moreover, you can buy oscar fish in pairs for breeding. Established breeding pairs are very valuable and can be even more expensive than buying the fish individually.
Additionally, their care and maintenance is also quite expensive. A single oscar fish needs a 55-gallon tank or larger, which can cost $300-$600. You also need a filter and a heater, which can cost $50-$100 each. Fortunately, oscar fish food is quite affordable, costing around $10-$30 per month.
When deciding whether to buy an oscar fish, you need to evaluate all the necessary expenses involved.
