I have two rhino nymphs that are 7-8 months old. I'm not sure of their sex. They went from being very inactive to exploring their enclosure on a daily basis since I cut their substrate down a couple of weeks ago. Their newest odd behavior is sitting with in a corner, one standing on top of the other. I was wondering if anyone has seen this before. From what I understand they are way too young to mate, and if it's a dominance thing, I should probably separate them. Any advice would be greatly appreciated!
