Sable Gravel is a beautiful substrate that showcases a range of dark shades, from grey and black to brown and even ochre reds.


Stream Gravel is a perfect choice for aquarists who want to create a natural riverbed in their aquarium. The greyish stones have a slightly rough texture that mimics the appearance of stones found in high mountain streams. The gravel can be used alone or in combination with other gravel or sand to create depth and complexity in your aquascape.

The slightly rough texture of Stream Gravel provides a natural-looking substrate that enhances the appearance of your aquarium. The gravel’s greyish color creates a stony riverbed impression, making it ideal for creating high mountain stony stream biotopes.

Stream Gravel comes in three size mixes (S, Mix, and L) to suit different aquarium sizes and layouts. The S size mix ranges from 8-20mm, the Mix size mix ranges from 8-40mm, and the L size mix ranges from 20-40mm. This variety of sizes allows you to create a more natural-looking riverbed by combining stones of different sizes.
