FHM in a water body without predators will usually stay in deeper water for security from over head predators (mostly birds). When swimming predators are present, the predators "push" the FHM into the shallows where the FHM and many other species of small fish instinctively seek the shallowest water and larger predators have a little more difficult time catching small fish. This security doesn't last very long for the FHM.
