Yes, fish tanks generally need gravel. Aquarium gravel is an important component for a healthy fish tank environment.
Here’s why gravel is beneficial:
- Beneficial Bacteria: Gravel provides a surface for beneficial bacteria to grow. These bacteria are crucial for the nitrogen cycle, which helps break down harmful fish waste and maintain water quality. This is according to our reference which states, "Aquarium gravel is an important component of any fish tank. It will have beneficial bacteria, helping to create a healthy environment for your fish."
