Do you need a tank stand for 5 gallon fish tank?

Yes. A tank stand is necessary for a 5 gallon fish tank because it provides stability and support for the tank. It helps to prevent the tank from tipping over and causing injury to people or animals in the area, and also helps to distribute the weight of the tank and its contents evenly, preventing the floor or other surfaces beneath it from being damaged. Additionally, a tank stand can help to raise the tank off the ground, which can help to prevent the water from becoming too hot and provide better viewing of the tank.
