I love these little guys, but unfortunately most do not survive. The only advice I can give is to baby the mess out of it. No direct light--just filtered bright indirect, bottom water it, and pray. I have heard that if they survive to a certain size that they can be micrografted to a root stock or another Adenium, but I have never seen this work successfully anywhere.
Good luck! Welcome to NGA! Keep us posted on your growth
Edited to add: Feel free to pop over to the Adenium forum and feel your way around. Lots of very knowledgeable individuals there.
