To breed pacu fish, the tanks must have a capacity to hold minimum 50 gallons of water for juveniles and at least 200 gallons of water for adults. The tank water must be filtered regularly and the temperature should be maintained between 23 - 28ºC. Also the pH balance of water must be maintained between 6.5 - 7 and the hardness up to 20 dH. It is recommended that fish tanks have enough hiding places as these fish have prey hunting habits. Juvenile pacu fish enjoys the company of other fish but as they mature, they tend to become solitary by nature. But generally, they have a mild temperament and get along well with other species like Oscar fish and Clown Knife fish. At times, pacu fish are also bred in indoor ponds.

Tonight I will see where I can find 50 or so of these. Any ideas please let me know.
Here is an idea, don't. Whoever wrote that article is an idiot. 200 gallons will not even cover the first year of growth. Mine grew from 2-3 inches to 18-20 inches in about 6-7 months. They are called tank busters for a reason. And spawning works on an industrial scale in enormous ponds, not an aquarium. You would also have to hit all the stores in your area to find that many at once. Then they would just get more and sell them to others who would not be able to care for them and end up suffering or being released.
