I just happened to glance as I was walking by my deformed guppy habitat. All the girls with messed up spines have their little harem. And. I saw fry. So I stood there and watched, figured out which girl was giving birth and separated her. I actually got to witness her pop out 5 fry. It was pretty amazing. All my fry are hanging out in a little ghetto makeshift tank with a heater but no filter. Only 8 of them. 50% water changes daily with Prime. They're happy little buggers. Seems to prefer the "First Bites" over every other food I have offered.
