Pregnant Fish?

[jwddboy]

However... you really need to get another tank if you want to keep those fish or any babies you will have.

To be quite honest is she DID have fry, they weren't eaten and did start to grow then it's likely they would die in the water conditions that amount fish will create, along with some of your other fish.

Would you mind posting your water param?
Might be easier to diagnose it as bloat or some other thing (if it is) if your water param are bad.

(one quick thing... unless its just the photo... i think this is a pearl danio)

Ph is around 7.6

and Ammonia is 0 ppm.
