Day 2 of #SlugsVsFishes is feeding and predation. As you know, fishes for that covered real good. If there’s something edible in the sea, fishes will find a way to eat it. Acanthurids, like this Zebrasoma, are herbivorous. They feed mostly on algae and other vegetal growth. 1/- Surgeonfishes have long guts with specialized bacteria that help ferment and digest plant matter. They are effective grazers and provide important ecosystem services by clearing filamentous algae in young reefs, allowing corals to colonize and grow. #SlugsVsFishes 2/-
