To freeze a fish in its place, select "Create-a-Fish". After your fish is created, chase a fish. If it runs, press [Esc] to pause the game. Move the pointer over the fish, then and click and hold. If the caption states that the fish is "Looking for a place to hide", chase a different fish. If it states "Running from" your fish, resume game play. The fish will stay in the same place until eaten.
