I got 2 female guppies from the store and both of them are pregnant. 1 of them is quite a bit more pregnant than the other 1. I don’t know for sure when they are going to give birth. Neither of them are very fat but one of their gravid spots is dark and the others is medium colored, but I had a platy thats gravid spot was only medium dark colored and I thought she had another week, but she gave birth the next day. So does any body know about when they will give birth?
