Galapagos Preserved Spanish Moss is ideal for Tropical & Forest Terrariums because it naturally grows in wet, humid environments. The locals call it “Old Man’s Beard” because of its stringy, long strands and spooky, southern feeling. Spanish Moss naturally grows hanging from trees, so it looks best dangling off branches like Jungle Wood, Spider Wood, or Mossy Sticks. It can also be used to decorate hides like Mossy Caves. Spanish Moss is 100% natural and safe for animals.
