This might be the stupidest question ever, but here goes. I haven't had to think of this yet because 2 of the 3 fish I currently have are sterile (glofish). But I'm thinking ahead to when I move them to my larger tank. I'll round out the school with 3 more glofish, but I was thinking of also adding in a school of guppies (3 at a time of course). And I've read that you should have at least one female guppy, correct? So what do you do with the little fishy babies that will eventually arise from this? I don't want to end up with fifteen thousand guppies in my tank. I don't have friends/family to disperse them to. Do you...get something to eat them? How would you keep that thing from eating your other fish?
