of the fish tank is about 5-10 centimeters away from the top. A certain space is reserved, which is beneficial for the water body to contact the air, thereby increasing the dissolved oxygen. In addition, different fish have different requirements for water level. Generally, small fish are used to living in water below 30 centimeters. If the water level is too high, it will form a larger water pressure, which is harmful to the health of fish. Larger fish can be suitable for 50-60 centimeters of water.
is suitable for high water level? 1. Arowana: Arowana is a common large tropical ornamental fish with a body length of about 40-50 cm. It has a ferocious temperament and mainly feeds on fish and shrimp. This kind of fish should not be raised in too deep water during the juvenile period, with a depth of about 35 centimeters, while adults should be raised in an environment with a depth of 60 centimeters.
2. Siniperca chuatsi: Siniperca chuatsi, also known as devil fish, is a benthic fish. Its body is flat, diamond-shaped or round, and its pectoral fins are very developed. Since this kind of fish lives at the bottom of the water, it can naturally adapt to the environment of high water level, endure strong water pressure, and has a good ornamental value.
3. Koi: Koi is a kind of omnivorous fish. It has a mild temperament and likes to swim in groups. It is relatively easy to raise and has a strong ability to adapt to water temperature. Wild Koi will swim to deep water environment in winter, so it can be kept alive in a fish tank with high water level.
