I don't know if it is a succulent in the sense of other things we usually call succulents here on the forum, but South African bulbs usually end up in succulent collections.
You may want to move it into a pot of its own. That plant will multiply like crazy and will start to take over your pot! This one was in a 4 inch pot (but has since been moved to a 6"). I didn't even realize how overcrowded it was getting until I took the picture.
