Hi! About a month or two ago I set up a tank with 6 black skirt tetras, but before I put the tetras in I did a fish-in cycle with some feeder fish (livebearers: platies & mollies). Most of the feeders died at first as expected, but a few of them survived. Since I didn't expect the feeders to stay alive, I wasn't prepared for taking care of them or doing any specific research. Anyways, my question is: one of the mollies looks pregnant. The 2 mollies are always following each other around and seem like a pair. I'm not completely sure if she is pregnant or not, but if it ends up giving birth, will the black skirt tetras eat the babies? My black skirts are not usually aggressive but can be nippy.
