It is a completely natural substrate composed of tiny, water-worn pebbles sourced from riverbeds.

Key Characteristics:

• Color Profile: It features an organic, earthy blend of deep browns, olives, tans, grays, and muted terracottas. The wet look brings out a rich, glossy depth in each unique pebble.

• Texture & Size: It consists of mixed small sizes (typically 2–8mm) with highly polished, smooth, rounded edges shaped by natural water currents.

Aquascaping Benefits:

• Ultimate Natural Realism: Perfect for biotope aquariums, riverbed scapes, or stream setups. It looks incredibly authentic when scattered around the base of larger hardscape stones and driftwood.

• Fish & Invertebrate Friendly: Because the individual gravel pieces are completely smooth and rounded, it is perfectly safe for bottom-dwellers (like loaches, catfish, and cories) and won’t scratch sensitive fins or barbels.

• 100% Water Inert: Being natural river stone, it is completely neutral. It will not leach minerals, modify your water hardness, or alter your pH levels.

These beautiful stones are Red Jasper pebbles (often referred to as Red Jasper tumbling/gravel stones or Fire Stone in the aquarium trade).

They are a type of semi-precious quartz known for their deep brick-red or terra-cotta coloring, naturally accented with striking white and cream-colored veins or patches of quartz and chalcedony.

Why they are great for aquariums:

• 100% Water Safe: Red Jasper is entirely inert, meaning it won’t leach minerals into your water or alter your pH levels.

• Vibrant Aquascaping: Their colors pop beautifully when wet and under standard aquarium lighting.

• Safe for Fish: In their polished, tumbled form, they have smooth, rounded edges that won’t scratch or harm bottom-dwelling fish.
