Are my minnows okay?

Hi all, a few weeks ago I stocked my first tank with 7 golden white cloud mountain minnows. It is a decently planted, cycled, 10 gallon tank. I also have 6 Pygmy corys with them and they get along great. They seem to be doing very well but they chase each other A LOT. The original 5 I got are colored up great and the 2 newer ones added a week later are still a bit pale but doing fine otherwise. I’m wondering if this behaviour is normal? A lot of chasing, flaring fins and “dancing” while flaring fins. They’re very active and fun to watch but I worry they’re being aggressive with each other. I’m not sure how many males vs females I have just yet. Any advice is appreciated!
