Recently, I've had a "bully" in my group, fin nipping all the other barbs, 1 in particular. Low and behold after a week of super aggression, he has calmed down, but alas one of the barbs without a red nose (female?) is showing quite a belly. I don't see the fish pigging out that much so I'm not sure what to think, how can I know for sure? They're a bit small to take pix, about 1.25 inches each.
