Why is gravel and substrate important for a freshwater aquarium?

Gravel and substrate are essential for freshwater aquariums as they serve multiple vital functions. They provide a foundation for aquatic plants to anchor their roots, create a breeding ground for beneficial bacteria, and offer a comfortable environment for fish to explore, hide, and forage. They can also impact water chemistry and help maintain a stable pH level.

How do I choose the right type and size of gravel and substrate for my aquarium?

To choose the right freshwater fish tank gravel or substrate, consider the needs of your fish species and plants. For instance, fine substrates are suitable for delicate plants, while larger ones suit burrowing species. You might also want to consider a gravel that complements the aesthetics and colour scheme of your tank. If you're unsure, we recommend discussing your options with an experienced fishkeeper or aquarist.
