Today I was feeding the FH and observing their behavior along the shoreline. I was feeding them fairly large Gamefish Chow and watching the water polo matches that resulted. Some of the largest minnows would end up in water so shallow they had to wiggle to get back out. I was watching a school of Gambusia sized FH when I saw an odd flash from one of them. It looked like it turned onto it's side suddenly and then stayed that way. I couldn't figure it out until I noticed that it was sporting one of
these . The FH got progressively smaller until it disappeared at which time the crawdad turned and retreated to deeper water. It ain't easy being a Fathead.
