Olibetta Black Zebra Stones, 60 (1 carton)

Black Zebra Stones bring bold contrast to your aquarium. These dark grey to black rocks have striking pale veins, making them ideal for creating distinctive underwater rock formations.

Product highlights:

• Distinctive zebra-like veining: Fine, irregular pale lines run through the dark grey and black stone, giving each piece its own character.
• Stronger contrast underwater: The rocks darken when wet, making the white veins stand out even more.
• Angular shapes: Varied outlines let you create dramatic formations, narrow crevices and changes in height.
• Easy to combine: The dark rocks contrast beautifully with pale sand, fine gravel, aquarium wood and lush green plants.
• Water parameters: These rocks can increase the hardness of your aquarium water.

Set contents:

• 60: 8 stones (6 M, 2 L)
• 80: 10 stones (7 M, 3 L)
• 100: 14 stones (9 M, 4 L, 1 XL)
• 120: 18 stones (11 M, 5 L, 2 XL)

How to use:

• Combine different sizes, using larger rocks as focal points and smaller pieces to create natural transitions into the substrate.
• Add mosses or plants such as Anubias, Bucephalandra or Java fern between the rocks to soften the transition from stone to planting.

A closer look:

Black Zebra Stones add depth and definition to an aquascape. Their dark colouring is crossed by fine pale veins, which become more pronounced underwater as the stone takes on a richer shade.

The angular shapes work well in both contemporary rock arrangements and mountain-inspired layouts. Pale sand or fine gravel brings out their contrast, while green plants and aquarium wood soften the overall effect. As these rocks can slightly increase water hardness, they are particularly suited to aquariums with inhabitants that prefer harder water, or layouts where water parameters are carefully monitored.
