I had another successful birthing this morning. Over 40 fry, possibly over 50. This is from a swordtail mom who killed most of her fry (I found only 11 hiding in the bushes) last month in a heavily planted 10 gallon single fish birthing tank.
Of course by rescuing these fry I am inadvertently propagating the genes responsible for the cannibalism behavior. To eliminate this behavior one would have to throw away any fish that show this behavioral trait, which in my experience is every albino swordtail I've come across since 20+ years ago
