I believe Pandas are pygmies, so the 5-6 in a 10 is about right. They do seem to be a little more sensitive though, so keep that in mind. I personally have fallen for peppers because they are active and attractive. I've been told pandas are less active, but the ones I had were pretty high energy. It never seemed like a happy active, more nervous than anything. I had a lady recommend albinos because they are both hardy and active, but I've never had one, so I just have to take her word for it.
