The Dancing Bones Cactus is a tropical epiphytic cactus, found growing on rocks and trees in South America. They will thrive in bright, indirect light. These cacti need more water than your typical desert cactus. Give it a thorough water and then allow the top half of the soil to dry before watering again. 

These Cacti are in an 8" pot.

The sap of the Hatiora salicornioides is toxic and they should be kept out of reach of animals.
