Our natural woods have been carefully chosen to recreate a wild and "wild" environment within your aquariums. The aim is to best imitate a natural ecosystem, full of imperfections and differences in shapes and geometric structures. All our woods are 100% natural and every single piece differs from the others in shape, size, color and weight. No two woods are alike. IMPORTANT: before placing the wood in the tank it is essential to immerse them in water for about 15 days and let them drain naturally. The water must be changed repeatedly.
