Well she has the correct uv bulb and we do dust the worms and feed the crickets etc on calcium suplements as this was my first thought. I did have to remove the plastic plants too as she seemed to prefer these to the normal plants.

As for mixing them together the viv is large with plenty of hiding places etc if necessary, we were going to get the male neutered too if necessary. Although Iv never had trouble with them living in pairs before.
