Baby fry male guppies

Yes. If he can catch them and swallow them he will. If you wish to keep and rear a few guppy fry then you should use a spare aquarium and have no fish in it except for the gravid female. Once she has had the young she should be removed too because she also will eat the fry. The babies(fry Whatever) will be hard to remove, so put the pregnant female in a tank that you want for the fry. good luck!
