Cork Bark Tubes for Orchids, Frogs, Lizards & Snakes

A hollow cork tube is the rare piece of decor that needs no assembly and no imagination from your animal: it’s a hide, a tunnel and a visual barrier the moment it touches substrate. Sold by the pound, with roughly one to two smaller-to-medium pieces per pound, these natural tubes suit everything from snakes and lizards to frogs, arachnids and mounted orchids. Your order ships direct from The Bio Dude — see our shipping policy and refund policy for how these orders work.

• A ready-made hide: the hollow interior gives snug, dark cover with two exits — exactly the qualities our guide to reptile hides says a good hide needs, in a form that looks like it grew there.
• Earns its place at height: mounted horizontally or wedged between branches, a tube becomes an elevated retreat for climbing species — our arboreal layout guide covers safe, stable placement.
• Humidity-tolerant: cork handles wet vivariums and dry builds alike, which is why it shows up in dart frog tanks and desert setups in equal measure.
• Natural variation: The Bio Dude can’t guarantee exact dimensions or tube width — every piece is real harvested bark, so expect character rather than uniformity.
• Simple prep: heat treated at the source; washing and baking at 125–200°F for 35–45 minutes before use is still recommended to clear any hitchhikers.

One good tube can anchor an entire layout — start with the hide placement, then build the rest of the enclosure around it.
