Half-moon fish

When you stand in front of the aquarium and watch the fish swimming carefree, have you ever asked yourself why some fish are round and fat and cute, while others are thin? What about the thin and flat ones? The body shape of fish can be described as tall, short, fat or thin, and everything is available. Then take a look at the water flow size of the water pumping motor and filter on the market, and how it is related to the size of the fish.
There are no different types of fish, and they rest in different environments of water flow in nature. Therefore, in the aquarium, we should also imitate the natural environment to create the size of the water flow. For example, most spindle-shaped fish rest in the water flow. In more turbulent places, you can use a larger pump to create a strong flow of water. Some round and flat-sided ones are mostly found in still waters. If the flow of water is smaller, we can use an external cylindrical filter or an upper filter. To create gurgling water, and some round and vertically flat fish mostly live on the bottom, so the water flow should be small, sponge filters can be used, but in aquariums with different sizes or less water, more consideration should be given to water flow. In addition to keeping the water in your tank, don’t forget to pay attention to the oxygen obtained by the fish, so that you can raise a tank of healthy and colorful fish.
