I was talking to a friend on the phone and I was watching the fish in my wifes 50 gallon when I noticed a small white thing dart into the plants. I kept looking to see what it was and it was a baby. I told my wife and she started looking all over the tank for more. I noticed that one of the female swordtails was pregnant a day prior to finding the baby. I was going to get a breeding net to save some of the fry, but I hadn't gotten to the pet store to get it. The pregnant swordtail was acting a little strange and staying near the bottom of a heavily planted corner of the tank. I told my wife to watch her while I go get a net. My wife watched her push out 3 babies like a fully automatic rifle. I scooped her up in one net and I started fishing for babies with the other. The other fish seemed like they were prowling for fry. They were all in that same corner. The female didn't want to have her babies in the net so I had to let her go. She went to the same spot and and pushed out 3 or 4 more babies. So now I have one net resting on the top of the tank with babies in it and I'm catching babies with the other. I caught all but one baby. The one remaining baby still hangs out in that corner. The other babies spent a couple days in a catch net until I got to the pet store to get the breeder net. We now have about 15 babies and the lyretail sword is pregnant. I got another breeder net for her or for the BN eggs, which ever comes first.
