vidaXL Volcanic Rocks - Red - 5-8 cm - 10 kg

The volcanic rocks provide a natural, red accent for the bottom of your fish tank or aquarium, creating a vivid underwater focal point.

Their natural shapes add colour and detail to your setup, enhancing the overall aesthetic while contributing to a healthier habitat.
