Do I need to put aquatic plants in the fish tank? What kind of aquatic plants should be planted?

Having fish and grass in a fish tank is certainly beautiful, but it will be a lot of trouble. When it comes to raising fish, a naked tank is actually the best. If you must raise grass, keep one with strong and thick leaves. Because koi will eat aquatic plants, eating them by fish can supplement vitamins, but aquatic plants will not grow well. Also, when raising aquatic plants, the water quality is too clear and the plants will not be able to survive easily; and the water is too turbid and fish will easily get sick. ; So it is quite complicated to create a natural ecology. You have to bury nutrients in the sand. If you are a beginner, should you raise grass or casually raise fish? The main thing should be fish. And the hot weather in summer is coming soon. The last step is to buy an oxygen pump. Oxygen consumption will be greater in hot weather. If there are conditions for filtration, it is very important. It can help maintain water quality and reduce the amount of water changes, which can make fish farming a lot easier.
