Fat or pregnant Pristella Tetra?

[Ben 590]

Hello.....I have had 4 Pristella tetra's in my new 20 gallon tank for 2 weeks. One of them has become quite large in the abdomen. I am assuming its a female, she seems very active, still eating, and healthy. Could she be carrying eggs? Will she just drop them at some point? Could she be bloated? I did see her poop.

Any ideas??

I have the same tetras, with a female doing the same thing. The most I can figure is that she's waiting to drop her eggs when she finds a suitable male.
