Hmm, I'm not sure. I've kept guppies for years. 6 I think. We just had a mass female die out. Every single female but one died. So be careful, I think one of the females who died had poop like you described. Cool thing though: some of the babies have been mutated. I think in the 12th gen a round tailed guppy appeared. And now a split tailed guppy appeared. We haven't bought new guppies in 6 years.
I only have 1 betta left, but he's a cool blue marble!
