To create glowing or fluorescent effects, special additives or coatings would need to be applied to the gravel, which could potentially be harmful to aquatic life. Additionally, the constant exposure to water and light in an aquarium environment may cause these additives to degrade or leach into the water, posing a risk to the health of the fish and other inhabitants. **
