Disocactus anguliger or commonly known as the fishbone cactus or zig zag cactus! Fishbone cactus has a strong, thick leaf structure which means it holds a lot of water in the leaves which is why it resembles the classic cactus plant. However, Fishbone cactus still needs to be watered slightly more than a regular cactus would. Allow your Fishbone cactus to dry out 1/2 way before watering again. Fishbone cactus enjoys bright light as well, and can tolerate bright indirect but will grow faster in bright light.
