Ric-Rac cactus (Cryptocereus anthonyanus)-AKA: Fish Bone cactus, Zig-Zag cactus, or Anthony's Ric-Rac.
This succulent plant is native to southern Mexico. Considered an epiphytic cactus.The unusual-looking foliage, which resembles fish bones, is the plant's most attractive feature. Although these leaves are smooth, if you look closely enough you'll see small, needle-like hairs just behind the buds and along the inner leaf edges. As with all cacti, these need to be handled with great care (in fact, gloves are helpful) to avoid painful *****. The Ric Rac is an easy maintenance plant, as long as your container drains well, the plant is pretty much happy. It's very important that this cactus be allowed to dry out some between waterings.
Since this is a succulent plant, it doesn't require frequent watering. In fact, it even tolerates some neglect, bouncing back readily once water is restored. The leaves store moisture and use this reserve during times of extensive dry spells, such as with overwintering when watering is decreased to about once a month. While Ric-Rac can handle some sunlight, it generally prefers to grow in bright shade. If you want to fertilize Ric-Rac, do so in spring once water is increased. If your cactus becomes overgrown, you can trim it back as needed, let the ends dry and callous a few days to use the cuttings to make additional plants and then stick them in dirt. Broken pieces can be used the same way.
