With the Zoo Med Aquarium Mopani Reptile Wood, you can make your little critter’s environment more entertaining and stimulating. This two-color African hardwood makes a beautiful addition to an aquarium or terrarium. It features a smooth surface, textured details and unique mottled colors, so it’s visually interesting. It’s also one of the hardest and densest woods available, so it immediately sinks and won’t rot. While any natural wood will leach tannins, which discolor your water, you can soak this wood in a separate container to remove extra tannins, then add carbon to your aquarium filter to help remove any discoloration.
