Fat, female or pregnant?

[ZoeNC1]

So I have a small school of 8 black neon tetras that I have had for at least a month now and suddenly one has gotten REALLY fat. I’d suspected a few of them to be female but almost overnight one’s belly has just gotten huge. I don’t have a good enough setup for it to really be pregnant and I haven’t seen any courting action (I had googled it) but for the past week and a half the lights had been off and I had been feeding a majority of frozen food (trying to help new betta, he’s doing much better now) but I am honestly baffled by this neon. If it is only a normal female has she hit fish puberty or something? How did she get so big? Or is it something else I should be worried about?
Thanks for any help you guys can offer

Looks like a healthy female to me.

Nice pics. Do you know the name of that plant? I love the purple patches.

It's a silk plant.

Yeah sorry to say it’s just a silk plant from petco one in a three pack which I found to be a pretty good deal. I’m too broke to get real plants and the tank is big so I’d need a lot of plants if I was gonna go that route.
But yeah sorry it’s just a silk plant

Ah, so it's a fake haha. Looks amazing though. I'm not in the US, so not really sure what kind of stuff is on the shelves at Petco. Thanks for replying.
