Whether you have an aquarium or a terrarium, Galapagos Cholla Wood Branchesrnare a great addition. Made of fallen desert cactus skeleton, these branches are porous and attract shrimps and other microfauna in an aquarium. They’re also naturally great as anchors for growing plants and contain natural tannins that help lower aquatic pH. In a terrarium, the wood acts as a great hiding spot or perch for iguanas, dragons, chameleons, geckos or birds. Branches are available in multiple sizes to fit all tanks. This is also great for use with aquatic turtles, terrestrial turtles, tortoises, aquatic amphibians, terrestrial amphibians, invertebrates, lizards, and snakes.
