under normal circumstances, it is better to use a smaller flavor when fishing for laotou fish in the competitive pool. This is because the old fish is relatively small, with a small mouth, and can swallow small particles of bait that are easy to bite. Using a smaller flavor can increase the chance of fish biting and improve the catch rate.

using a smaller flavor will also help lure the old fish to approach the hook actively. Laotou fish is a typical feeding object of small-particle bait. They are used to eating small-particle food as the staple food, and like to search and peck at plankton and benthos at the bottom of the pond. In the competitive pool, the use of small flavor can better simulate the food source of the old fish and increase the attraction effect.
