What Species Are These Fish?

[krissssssy]

I recently was given some fish as a present. I can't work out what species they are though..
Does anyone recognise these two?

 

[Wills]

Ahhh of course. How obvious now you mention it.
Haven't had mollies for a few years. Also forgot how territorial the males are.

Thanks
