So I bought some guppies for the kids a while ago and they had babies. Most of them were eaten by their vicious parents and our angry fish, steve. Well, steve eventually died because he hated being around other fish. At least, that's why I assumed he died, because he spent months in solitary confinement and grew comfortable living in alone in his plastic prison. A while after Steve died, and through several batches of cannibalised babies, the mother and all of the original family randomly died. Except for one lonely male and a super tiny baby that was strong enough and fast enough to escape death. This baby grew up to be a fairly hideous female, and they immediately started pumping out babies like no tomorrow. And they have survived. I mean a lot of them.
She's definitely ready to have more babies and I see no reason to stop them from pumping out retarded fish babies. I bet they will make really entertaining feeders for some carnivorous fish.
That's right, I'm raising retarded guppies. On purpose.
I've done this with platys. Go to the store and buy two different guppies. Otherwise they'll inbreed to all having dull colours like the chinese.
FYI: I'm not joking.
