I wanted to give a quick update. After few weeks of having the bass and largest bluegill eat the Optimal Bass, I began throwing in a few pieces of whole Aquamax Largemouth into the mix. Some of the bass are beginning to take it too.
The largest of the originally stocked bass are now at 11-11.5". One LMB pellet seems to be about all they can consume per meal. Thanks for all the input.
