I have got some new Guppies and the woman in the shop said they are pregnant. I have looked for all the signs which she seems to have ie) black gravid spot, belly shape almost like corners, she keeps ducking down to behind rocks and plants etc... Where on her body do the babies come out? How many fry do they usually have? How likely is it that they will get eaten? It is a large tank and I have 9 female & 4 male guppies and 7 neon tetras.
