I spotted one small fry, when I was feeding my fish aquarium, I looked and didn’t see any others. I couldn’t pin point which female popped the fry, soon put both females into a net on top of the fry container so if any more would fall thru the larger holes of the net. This came to me as a surprised as they both look the same as weeks before and they don’t have the boxed belly most people see before a livebearer gives birth. I think I stressed them out and they’re not laying other babies. How do I tell if all the babies were eaten? Since my angelfish munchies on newborns before.
