It will grow to the size of the tank. We had an Oscar in a tank that was too small for him, and he had a smashed in looking nose.

You can keep him in there for now, but eventually he will need a bigger tank. He will get any where from 14 to 16 inches long and will need a tank that is wider than this to move around. Oscars grow pretty fast so I would consider getting a bigger tank and not have to worry about swapping at a later date.

240 liters is only about 60 gallons. That is NOT big enough for a full-grown, foot-long Oscar (and especially a full-grown Oscar and a school of Silver Dollars). Keeping an Oscar in a tank this size for its whole life would roughly be the equivalent of keeping a Guppy in an 8-ounce glass of water.

One Oscar needs at least 90 gallons of water for long-term maintenance (120 gallons for two), due to their eventual large size, relatively high activity level, and hearty diet. An Oscar can be kept in a 60 gallon tank for about two years, but after that it will need a larger tank. If not moved, the water quality would decline quickly, allowing diseases such as Hole in the Head (which is most often caused by poor water quality) to infect your fish.
