There's no question that in my HSB pond, they attack the forage with abandon and do the same to any fly/lure that looks the same. In another two or three weeks, the big show will begin. We like to take a seat on the pier and watch the HSB in open water schools/packs tear up the forage which largely consists of slowed Tilapia. Its awesome to watch and makes me glad to have them in my pond. If we can reduce or eliminate feeding them pellets, then they would be the perfect fish for my ponds.
