Well I've got 3 males (2 pastel,1 normal) 6 females ( 1 pastel, 5 normal). All are of breeding size. I have witnessed several locks with all of my females. What are good signs of a gravid female? I have one normal female right now that is pretty thick right now but i never saw her (lump up) or lay inverted. Is there a tell tell sign they are indeed gravid or ovulating?

sorry for the long post, this is my first time trying to breed
