If you look at the Optimal Fish Food Pellets, that's what they look like - worms/grubs of different lengths.
It makes sense and I do remember the optimal bluegill I bought years ago being more pill shaped. It's interesting having the tank setup to observe feedings. Even the male BG which is an aggressive eater seems to struggle with the largest size pellet in the Aquamax MVP. They fit into his mouth but he spits them out and back in several times, I assume until they are soft enough or small enough to swallow.
