The tank should be rectangular in shape, the optimal size is from 15 m2, the depth is about 1 – 1.5 m, with a net around it to prevent the fish from jumping out (with hyperactive fish), with a roof. cover if the weather is inclement. With this area, the fish has enough space to work, so the productivity will still be high without being affected.

At the bottom of the tank, people should cover with a layer of sand, which acts as a buffer to prevent the fish from contacting the bottom, and at the same time helps to filter the water. The tank should be tilted towards the discharge direction.

Every time you feed your fish, you need to monitor the strength and clarity of the water so that you can take timely action when problems arise. Temperature, water environment, food quality or fish health will determine whether fish eat more or less.

When the fish are small, it will be better if people equip them with bamboo trays. Put the food in the blister, drop it into the water not too deep, about 5-10 cm for easy observation. When the fish is larger, you can drop the food directly into the tank near the drain so that when you discharge the food residues, it can be washed away.

Water environment for fish is an extremely important issue that needs to be paid attention to. The time it takes to change the water for fish also varies between different types of fish. For example, with snakehead fish, within the first 20-25 days, the water should be changed every 2-3 days. Until the fish is 1 month old, the water must be changed daily.

In the months close to the harvest time should be changed 2 times / day. Some creative and qualified farmers in terms of land area also apply the method of building many tanks to raise many different types of fish, installing a pipeline system to bring water to the lakes, waste water from the lakes. The snakehead fish pond will be taken to the catfish pond, helping to make full use of the leftover food.
