Ive been breeding for 3 years, and all 3 years were a complete sucess for me. Now my bee male (proven) just wont lock up with my female pastel. The pastel is 1900+ grams but they wont lock up. I tried leaving a tissue with another male and puttin it in with them, and that didnt work. Im not new at this so i know what im doing, but i cant seem to get them to breed. Any tips?
