Zebra Danios Female Egg Burden?

[101DalmatianMollies]

Hello!

Almost two years ago when I set up my 10-gallon, I purchased 3 silver zebra danios from Petsmart as my cycling fish. They're so cute!

They now live in my 33-gallon with the rest of the community crew, as the 10-gallon is reserved for my pleco breeding (which I think after this batch I've had my fill of haha)

I noticed recently that one of the fish, who seems to be a smidgen (and only a smidgen) bigger than the other two, has a swollen belly, almost as if she's pregnant? (obviously with eggs). These guys are difficult to sex, and I'm not 100% sure the other two are male, as their size difference is almost negligible and now they're starting to look a little portly as well.

That being said, will she eventually pop out her eggs? They're still active and eating etc. I just feel bloated watching her swim around like that.
