Even if each species of fish doesn't take to the feed directly, feeding is still a huge benefit. The fish that do eat the pellets directly gro faster and are more health, spawn heavier and provide more forage for the fish not eating the pellets. Excess feed provides more fertility for you to feed on and the feeding frenzy when pellts are distributed provides an opportunity for non-pellet feeding fish to grab an easier meal of a feeding fish...it's a win, win situation.
