Male sugar glider being aggressive to young cagemate

For context I have an about 4 year old make and a year and a half female. The male Will consistently chase, swat, and hiss at his companion. All goes on to a point she can not go to bed without him going after her for hours at a time. They sleep together all the time play all the time when I can get the male out. I’ve changed their feed multiple times and made sure to keep multiple feed stations. They have plenty of toys, stuff to chew, enrichment treats etc. the only thing I can think of is the two gliders sharing a wheel
