Nudibranch - Elysia Ornata? Good or bad

[Rbgetz]

Hi.. New beginner guy with a new build on a 29g JBJ Nano. I'm 11 days into my cycling and finding all sorts of new things, 2 crabs, aiptasia's and today I found this little sea snail. I'm really new with all this and read threads and did some research before writing, but this looks like a Nudibranch to me. Looks like a Elysia Ornata. Can someone verify and is this reef safe? Would like to know before I start adding new "things" to the tank. Only thing I added has be a handful for red legged crabs. I hope you can see it in my photos..... Rob
