They are non-obligate egg feeders, but a lot of people find the neonates to be fragile. They seem to like film canisters placed on the ground and tilted to be mostly horizontal (like a cave). That also makes it easier to collect eggs. If this your first dart, I'd highly suggest something more like tincs, leucs, or auratus. Retics are a lot more touchy than those, and can squeeze out of very tiny spaces.
