I agree. They congregate into groups for the ease of feeding. Mainly to overwhelm resident damsel fish with sheer number and eat their algae. Some sharks also group together during feeding, but we dont consider them shooling either.
Even fish that truly school in nature generally stop doing it in captivity unless they are kept in massive tanks with predators. For example freshwater neon and cardinal tetras school in nature. But in an aquarium schooling will only last for couple of months. After that, they will separate into multiple small groups or hang out on their own.
