Substrates & AquascapingBuce Plant
Ghost Wood is a natural aquarium driftwood that starts pale and weathered when dry and transforms into a rich, deep mahogany once submerged; smooth, sandblasted trunks and sweeping branches give a clean, sculptural look ideal for defined, mature layouts. Equally popular in vivariums and terrariums where it will not rot easily in high humidity. Naturally aids in softening water for acid-loving fish and shrimp. Sizes from XS (under 10 in) to XL (30-38 in); single, 3-pack, and 5-pack options. Leaches fewer tannins than Malaysian wood but may add slight tea-colored tint initially.
