Mopani Wood is a beautiful two-toned African hardwood which makes an amazing addition to any tropical freshwater aquarium or terrarium. A smooth surface and textured detail adds an awesome natural touch to any environment. The extremely dense hardwood sinks immediately and won't rot like driftwood, making it perfect for aquatic setups. Each piece has a unique shape, crafted by nature, and has been sandblasted clean so it's ready to be added to your aquarium or terrarium. Use with plants to create the "naturalistic" look.
