I'd see one fish swimming in the pond followed by anywhere from 3 to 10 other fish. I'm assuming that was one female followed by a school of suitors.
Scott...the male builds a nest and will not leave it. He'll chase all fish away, including gravid females until she is within hours of laying her eggs. As soon as the eggs are laid, picked up and fertilized, the male will kill her if she stays close to the nest.
