hiya, the pic u posted is identical to my guppys. if it was a swordtail she wudnt have a very guppy like gravid spot.
the fry look similar to mine, but i cnt be sure, as they are sooo small.
i wud just wait til they are grown abit, post another pic, and let ppl help u decide if they are swordtail or guppy fry. but im pretty sure they will be guppys.
