Answer 2

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.

Answer 3

The thing I read was along as your fish is able to turn around comfortably than you should be fine, so if your Oscar grows to a foot(and it will) then you will need a tank that is wider than 12" I don't know the dimensions of your tank but as long as it is more than 50 US gallons you should be fine. But keep in mind these fish are very messy and will need excellent filtration and keep up the water changes

Answer 4

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.

I worked a large aquarium store while I was in high school, and in that time customers had brought in probably 100+ adult Oscars that had been kept in too small a tank. And ironically, not one of them was purchased at the store where I worked (they were blindly sold to these people by large chain stores).

The condition these fish were in when the people brought them in was appalling - the majority of them had bent spines, calloused faces, and Hole in the Head so bad that the holes were going through the skulls. All of these conditions are caused by poor water quality and too small a tank. Most of the fish brought in were on the verge of death, and we had to humanely euthanize them.

So like I said before, you can keep an Oscar in that temporarily, but it will need to be re-housed in the future. Plan on buying a larger tank or finding someone who will be able to take the fish and keep in in their larger tank.

Hope that helps.

Answer 5

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.

Answer 6

yes you cna thay grow to be big but it should be fine
