Fighting the seasonal monsoon floods is an almost daily chore for businesses in Vietnam's Ho Chi Minh City, where guests often seek refuge from ankle deep floodwaters in the city streets in cafes and bars.

Those looking to dry off might want to avoid the Amix Cafe, where guests enjoy their coffee with water up to their ankles as fish swim around their feet.

From the ground floor, Amix does not seem any different from other modern cafes in the country, with an attendant behind the shop counter, a board with the menu and several tables and chairs.

However, visitors who decide to go to the first and second floors get to enjoy their coffees as Japanese carp swim around their feet.

The idea is the brainchild of Nguyen Duoc Hoa, 23, who opened the business in June last year with the aim of bringing another dimension to popular cafes where people entertain themselves by petting cats or dogs.

"I wanted to create a unique concept, that did not exist in any other place. I am from a coastal city, I love fish and thought it was a good way to create a business combining innovation and my hobby," he told EFE.

Kick-starting the business was not easy due to technical complications and the cost of flooding two floors of 20 square meters (215 square feet) up to a height of 25 centimeters (9.8 inches) - requiring 5,000 liters of water on each floor - as ell as keeping the water clean.

Hoa said they use a triple filtration system and air pumps to keep the water crystal clear, changing a quarter of the water every 12 hours to maintain optimum cleanliness.

As Hoa explained the details of his enterprise, visitors kept flowing in to the cafeteria - three girls who looked like students and two mothers with three children.

The little ones swiftly removed their shoes and socks, washed their feet and entered the water, although their mothers were more hesitant.

Families with children go to the first floor where there were some hundred small-sized fish, whereas on the second there are some 20 Japanese carps, each one weighing some 300 grams (0.7 pounds).

Hoa said that families and teens were there main clientele, and that generally they prefer students or young professionals to young children.

Hoa said that families and the youth were the two major groups of clients they had, and their experience with students and young professionals were more positive than that with families.

"Most families don't cause any problems, but there have been some naughty children who try to catch the fish, and their parents don't say anything. We have had to invite them to leave", Hoa said.
