so I've had this one male guppy, he's a wild type guppy for a few months now and today I got him a female fancy guppy to see if they would mate. They're in a community tank with one female betta and 3 neon tetras, I plan to move the neon tetras if I get any fry. So far the male has been trying to make a move on her but I think she might be resisting, either that or it's normal, I'm not sure as I don't have any experience in breeding yet. Could she been pregnant already? I got her from a place that separated males and females but she could have already mated with a male before being separated, I really am not sure. The male was going at her nonstop for about an hour when I first introduced her in the tank but stopped for a while after, he's back it again though. I DO want to breed them so if you guys could give some tips then that would be great! one other thing, the betta is quite docile and doesn't ever attack the other fish in the tank except for a quick chase at the male guppy a couple times a day and she also only goes up to the female guppy and the female guppy just swims away, and the neons, she doesn't bother with them as they're much too quick for her and she knows it
