Father wants to raise fish in a small pool of four or five square meters behind his home. What kind of fish is better for swimming pool?

It is suggested that things go to rectangular pools. It should not be too deep, not exceeding1.5m. The wall of the pond can be steep, or it can be surrounded by dams or bricks. Drainage holes should be left to prevent fish from leaking in rainy season. Plant flowers and plants on the south bank, or plant loofah and lentils on the shelf above the pool. You can grow lotus flowers and bamboos in the water. Create a cool and quiet environment. Because there is little and shallow water. It gets hot easily in summer. Conditionally put an aerator. The water is really small. 4.5 square. . . . Suggest the earthen pond. You really need a cement pool. Must be scrubbed many times. Soak. Better change more water in the sun.
