Pham Hung Thinh and the koi fish pond
Thinh then went to learn from other fish owners online.
As of now, his farm covers 300 square metres with all required equipment. He is raising 6,000 koi fish. According to Thinh, the ponds must be 0.8-1.5 metres deep and the water must be clean with a pH of 6 to 8. A koi fish is sold for VND350,000 (USD15) per kilo. Koi fish whose parents are imported from Japan cost VND550,000 per kilo.
"When you first raise the fish, it's better to mix salt into the water to help the fish adapt to the new environment and treat the wounds they may suffer during the transportation," he said. "The koi fish was sold at several weeks old or up to three months old. Bigger fish are more expensive."

"I have to "hunt" for rare and healthy fish from other farms to breed. It's a really time-consuming task so you have to be passionate," he said.
Thinh plans to expand the farm to import more koi fish from Japan. The imported fish cost several million VND per fish. However, Thinh said he had a lot of customers searching for them.
