What is the primary dietary focus for the Wrought Iron Butterflyfish compared to shallow-water relatives?

Answer

Benthic invertebrates found clinging to or hiding within rocks and rubble.

The feeding specialization of the Wrought Iron Butterflyfish is adapted to its deep, rocky habitat, causing it to differ significantly from relatives that inhabit sunlit reefs. Its diet is centered almost entirely on benthic invertebrates—small organisms that live on or within the substrate. This means the fish forages by meticulously picking at the rocks and rubble for small, perhaps sessile, organisms, contrasting sharply with shallow-water species that might engage in broad grazing activities across large coral surfaces or consume coral polyps directly.
