1. How big is the fish tank of Betta? Betta is a kind of fish obsessed with gills and does not need much living space. Just choose a fish tank with 15* 15*20. Betta is fierce by nature, so it's best not to provoke it. Betta can also be kept in a fish tank of 10 cm. The water in the tank is at least 3kg, and the water depth is at most 20cm. But pay attention to the influence of water temperature and quality. Because the fish tank is not big, the water quality problem will be more serious, so it is necessary to change the water regularly, control the water temperature at 22-24℃, and keep the acidity at 6.5-7.2 to ensure the stability of water quality.
Second, how to put the fish tank in the betta fish tank should be placed in a well-ventilated and well-lit place, and at the same time pay attention to the lighting time. Some barriers should be placed at the bottom of the fish tank, such as some pebbles, aquatic plants and other algae plants, which should not contain calcium to ensure the cleanliness of water quality and increase the oxygen content in water. Placing some bottom sand can help stabilize aquatic plants and facilitate the attachment of microorganisms in water. The best water-sediment ratio is 5: 1. But don't arrange some rough or sharp substances in the cylinder to avoid hurting them.
You can also choose white sand and heavy wood. Heavy wood can change the acidity of water, make it more and more sour, make it more suitable for fighting fish, and provide them with shelter. Filters, heating rods, thermometers and other equipment should be placed in the fish tank to provide them with a more comfortable living environment. It is best to put a small light with softer light in the cylinder.
