Thanks guys! The nem took a long walk down through the rocks where I placed it around the back wall and it just popping out now on the back left side. Not my ideal choice for him but hey thats what they do right!
it will be interesting to see if it stays there once the light comes on. As long as it stays at least half way up and towards the back I'll be pretty happy. Even though it's current location is not ideal it would showcase all the different nem colors really well!
