This is kinda an odd question, but in one of my tanks I have a few different kinds of fish for breeding. Well, out of all these I have one male guppy and one female swordtail. The male guppy seems to have taken a . . . Liking . . . to my swordtail, if you know what I mean. Well, that was about a week ago and I noticed the other day she appears to be pregnant. Is it possible for a male guppy to get a female swordtail pregnant?
