Nets are a vital tool for keeping fish tanks clean and tidy. They come in a variety of sizes and materials, making them suitable for different tank sizes and types of fish. Nets are used to scoop out debris, algae, uneaten food, and other floating materials from the tank. They are also used to capture fish for relocation or cleaning. Nets can also be used to separate different types of fish that may not get along in the same tank. Nets are an essential part of any fish tank cleaning and maintenance routine.
