The Wang brothers' fish farm was a big pond that they cordoned off to cultivate Arowana specifically.
They started their business four years ago and when they heard about the great value of Arowana, they put in some money to buy a couple young Arowana and sectioned off a part of the pond just for these fish.
In the first two years, the Arowana were still growing and were too small to sell. Last year, they sold eight of their fish, but because the quality wasn't too great, they only sold the fish for one or two thousand each. In the end, they decided to wait one more year.
This year, partly because of their carelessness, the color and shape of the Arowana became worse and worse, and even though they were all more than seventy cm long, the value of a single fish wasn't even a thousand.
