Big belly white mountain cloud minnow - chubby or pregnant?

This is one of my white mountain cloud minnows. I got it along with 4 others about 2 months ago. Its been this chunky ever since I bought them, swims fine and seems to have no issues other than its big belly. Is it carrying unfertilised eggs or something?

Here’s the link to a video I took of it
I’ve seen a few tiny tiny fry in the tank but think theyre from my danios as I always see the danios actively ‘doin the dance’ and grew one of these fry up which turned out to be a danio. I never see the minnows doing any kind of mating type activity, bur maybe I dont know what to look for.

Basically, is this minnow okay? Or should I be concerned? Any advice is appreciated. Hopefully the picture next to another minnow gives you some scale

Looks like it has eggs in it. It may or may not lay them. If it does end up laying them, they probably won’t be fertilized.
