The Mistletoe Cactus is a succulent, epiphytic cactus which tolerates a wide range of conditions. It needs a well drained soil and if this is constantly and evenly damp, without being too wet then it will thrive. If it does dry out however then the succulent leaves act as a water store and it will draw on this to survive until it is watered. It dislikes bright light and is best grown in a lightly shaded position. its ideal in a scrub or desert terrarium if potted so that it can be watered.
