I've heard of tail wagging but never really knew exactly what it was or what purpose it has in breeding behavior. I introduced my pastel to my normal female tonight, about 2 hours ago. When I went up to look for my camera (still can't find the darn thing) I happened to look over at my female's tub and I saw her tail up in the air. Is this tail wagging? What is the purpose of tail wagging? To let the male know she is ready to breed?
