It isn't so much a matter of size.; these fish take at least two years to mature and can't be sexed easily; one method to get a breeding pair is to raise about half a dozen in a large tank (200 gallons or more) to let them pair off naturally.
The best way to acquire a pair is to purchase a proven pair of adult breeders.
Be sure you have a breeding tank setup too, there requirements for a breeding tank and the layout which is not the same as the regular aquaria; the tank should be at least 100 gallons. No gravel, rocks plants etc. It will take about a month for the pair to get used to their breeding tank.
One or two power filters, one on each side of the tank to try and keep the water clean; clean water is very important when breeding fish and raising fry. This is almost an impossible task with Oscars because of the massive amounts of food that they eat (live goldfish, frozen krill, almost everything but the kitchen sink!) and their appalling table manners. You'll be changing 10 - 20% of the water every day so this will help. When the eggs have been laid, you will turn off the power filters and set up an air stone or to at the opposite side off the tank of where the eggs are. You'll need a heater of 500 watts or two at 250 watts. Not the submersible types, the kind lets you adjust the temperature from outside the tank.
All little more then what was asked, but I could go on about what to look for when breeding time begins. Any more questions, just ask :)
Take care,

∙ 14y agoOscars are quick growers if they are fed and housed properly They will reach 12 inches long in a year and should reach 18 inches (fully grown) within 2 years. A recommended tank size for a pair of Oscars is 8 feet long by 2 feet high and 2 feet wide.

∙ 14y agoHeaps. a pair of Oscars need at least a 50 gallon tank to themselves with a permanently running filter and weekly water changes of at least 50%.
Wiki User
∙ 15y agoA single Oscar would probably survive in a 3'x18"x18". But I would not advise keeping an Oscar in anything smaller than a standard 4' tank.
Wiki User
∙ 14y agoI have seen them over 12 inches long but I am sure they will get much larger in good roomy conditions given time.

∙ 9y agoOn average, an Oscar fish will grow to about 12 inches with proper care. There are some rare instances that they will grow to 15 inches.

Is the silver dollar fish compatible with a baby tiger Oscar?
very much so, best companion Ive found for my oscar, I have 4 in with my tiger oscar, they stay out of his way if he has a tantrum, and he swims with them at times. I removed them once and put them in a different tank, and my oscar got so depressed I had to move them back. Silver dollars do get to a good size, make sure you have room, they are schooling fish so you need 3 or 4+.
How much room does a violet goby fish need?
Depends on how big it is.
Why does a fish need a certain amount of gallons of water for a fish?
There are quite a few reasons, but some common ones are that some fish need room to grow, some fish need room to swim around, and some fish need room to claim a proper territory.
Can you keep 2 Oscar in a 135 gallon tank with some different fish in the tank ant the weaker one be OK?
It all depends on how much other fish you have in the tank. Oscars need a lot of room so if there's tons of other fish in there it could cause problems. But if you have a couple it would be fine. If its a male Oscar its probably best you don't have them in a tank with any other Oscars. I volunteer at a pet store where they sell the fish so that's how I know this..
Are Oscar fish social?
Almost to a fault! Oscar fish are very social and in the wild spend a lot of time playing with each other. They are by far some of the most intelligent fish out there. In the absence of other fish they will begin to consider you their playmate. Many oscar fish will learn to wait at a certain corner of the tank because they know you are normally home at that time. They will swim around in excitement when they see you, and follow you with their eyes as you walk around the room. My friends oscar would often watch us watching TV, sometimes he would watch too. He seemed to really like the Harry Potter movies.
Why do Oscar fish need to live alone?
Oscars should be kept alone so they don't eat any of your other fish of fight with other Oscars. Oscars also grow very fast and as they do they become more and more aggressive. They can sometimes be kept with a large plecostomus if your tank has plenty of room.
How will fish react with room temperature water?
They won't react at all, because fish need to be placed in room temperture water every time you change their water.
Why do fish need warm water in their tank?
fishes must be at room tempature
