One of my Tetras look extremely fat...prob because it's a female (Morwen) and is pregnant. Pippin, a male Tetra, seems kind of aggressive towards the other Tetras when they get close to Morwen. Is there any way I can stop this? I don't plan to raise the fry or take care of them because I don't have the food for them and I can't protect them from the other fish. Anything I can do?

Tetras are egg layers so are not technically pregnant, but gravid. I doubt you'll have to worry much about the fry. Your other tank inhabitants will no doubt eat most of the eggs before they ever hatch and any fry that manages to hatch out will be a snack.

Ok thanks
