Thanks for the input, the thing is though, I've had females drop fry in my 20g and I've only ever had 1 figure out how to hide well enough that he made it to adulthood. I feed live food about once a week so I think my fish have learned that small swimming things are fair game or something, not sure, either way guppy fry don't tend to survive in my community tank. Also, since I want to try and hybrid the guppies and endlers, i want to be able to keep everyone separated, I want to know who the parents are and see which crosses make the coolest looking babies. That is why I'm wondering whether one of those net breeder things (like this) is a good way to do that, or if I should find a spot for a fry raising tank.
Also....pygmy guppies?! sounds cool!
