My Betta has started chasing my glassfish all round the tank, I don't think he is nipping at them, just chasing them. Is this anything to worry about?

Since no one else has responded to your post I will. The only thing I can think of is that she showing your glassfish who's the boss. Hope that helped.

I didnt even know you could keep other fish with a betta, thought they were too aggressive or something?

Nah, they are fine with 'most' other fish. You just can't mix male betta's together.

your betta is showing dominance but sooner or later it CAN turn into aggression so id keep an eye on them if you dont wana lose any fish!

Totally agree, however, if he has only recently been added to the tank, it may just be a 'phase'. When i added my betta to my tank with a rescued dwarf cory (i know he's on his own, but finding dwarf cories are like finding rocking horse poo round here, the LFS himself didnt even know he had him! And to be fair, he's not that keen on 'busy' tanks, he was pretty traumatized when i got him. Hes a lot happier now and has a wicked little character, lol) he chased him about quite a bit. After a week the betta and the cory have settled right down and are quite happy together.
It is also worth remembering the bettas do have 'mood swings'. sounds a bit daft, but one day they can be ready to take on the world, the next be as soft as a kitten.
I would definatly keep an eye on it though. Should hopefully settle down once he feels a lot more 'at home' to the tank he is in
