The neon gravel looks great in my 20-gallon tank. My fish seem to enjoy the surface, and the water clarity has improved since adding it. No discoloration after two months of use.
Christopher Newman –
It’s a nice addition to my planted tank. The size is perfect for small fish and helps with root anchoring. I didn’t notice any fish behavior changes, which is a plus.
Victoria Slater –
Easy to install and looks vibrant under the tank light. The gravel holds up well and hasn’t faded or leached any colour after several weeks.
Christian Wilkins –
The neon effect is eye-catching, but the gravel is slightly coarse for very small fish. Might be better suited for medium-sized tanks.
