Oops

I found an oops in the fish tank last night. About a month ago, I bought a girlfriend for the boy swordtail. His name is Legolas. I've been looking for baby swordtails and wondering what's the hold up. These fish are livebearers so you have to put them in a net cage or everyone has a snack. I noticed that the girlfriend was growing a sword from her tail. That's bad you see because only boys have swords. (Get your mind out of the gutter.) Does anyone need a boy swordtail?
