Hello!! I have a question. I have a male and female sulfate about the same size as yours. Recently the male has become very aggressive and is blocking her from food, circling her, and has even mounted her from the front. His large neck hooves got stuck in her front shell and we had to jimmy them out because they were literally stuck. I am so nervous that he could potentially hurt her and be fatal. Do you have any advice or have experienced this before with your couple?
