Ha, Hyperion got so excited about his lady that he mated with her who knows how many times over the last 5 days AND left plugs allllll over Eris' cage. He is dark now that he isn't with her.
That is exactly what my BB ambi looks like when he is in mating mode. The pic is 30 minutes after removing him from the females cage when he started looking for her again.
Setting off a male Panther can be as simple as the barometer moving up or down in very a short time span. If a storm front came in or left your area, it can trigger the male into mating mode.
