yea, it was hard for me to get a pic of him cause he was so small and I was to scared to hold him haha. You definitely have to put a pic up of the nano!!! I have tried to keep pom pom crabs and couldn't so I stopped trying. But that would be cool if he turns out to be one and I can manage to keep him. Still haven't seen him since I put him in the sump. He's about the same size as some of my amphipods down there haha.Have to see from the front, but also agree he looks like a pom pom crab. I have one in our nano (your old one Traclly) and they are very reclusive. Probably lost his nems and feels real defenseless. They are funny to watch- boxing the nems out at you "I'll sting you..back up, back up"
