tanks too close?

[jasond02]

I have a male and a female beardie and I have their tanks side by side with a piece of cardboard between them to keep the beardies from seeing each other. The male is about a year old and the female is around a year and a half. She keeps going to the side that his tank is on and scratching at the glass. Can she hear him in his tank? I know when I take the cardboard down they either start waving to each other or he will black beard her and start head bobbing. Just wondering if I need to move his tank farther away from hers. Thanks!

I think she can probably smell him and sense that he is there.
