Platy chasing?

[Dyood]

my male platy who was calm and didn't do anything for weeks has decided to chase the females in the tank, I have 3 female platys with the one male, but I'm not sure if he is chasing to breed or chasing to be a bully.

He is also chasing my 3month old possibly female swordtail aswell, but not bothering with the older and bigger swordtails.

So my question is does he sound like he's chasing to be a bully or is he chasing to breed?

Sounds a bit like he's trying to spawn.

Breed, I had one that did it too. Unfortunately he was only chasing 1 of my 3 females so I had to give him to the lfs.
The males can be relentless.
