Our natural Decor Wood is carefully selected, graded, cleaned and does not float. The natural two-tone colour of this mopani wood makes it especially attractive in all freshwater aquariums. The Decor Wood is graded and sold in four different sizes with approximate weights of 0.5kg, 1kg, 2kg and 3.5kg. All pieces are tagged with water and tear proof plastic tags for easier selling and pricing. Also great with reptiles and amphibians.
