Is my swordtail trying to spawn? She has been sitting on a braod leaf for two days kind of wiggling back and forth, so her fins and tail are moving but she's staying in the same place. She's a pretty big female, about two inches long and there is a male in the tank about half her size. She has stopped twice to get something to eat then she goes back to the same place and wiggles for hours and hours. I don't think she's sick, since she is eating and her colour is fine. The other fish are pretty much leaving her alone, and the male swordtail only stops by every once in awhile. Does anybody know whats up?
