He is making htem incase a female comes by. If one does come by, mating is very violent, male could even rip some of her fins. After mating, female lays her eggs, and male takes care of them cleaning them and such. So basicly, they feel comfortable, and it's a goood place to raise kids!!!

^Sometimes females are more aggressive then males when breeding.I have heard stories on my betta forum when the females beat up the males.
