What is the primary food source for the Wrought Iron Butterflyfish in the wild?
Answer
Filamentous algae
The foundational element of the Wrought Iron Butterflyfish's diet while in its natural habitat is filamentous algae. This species is observed engaging in constant foraging and grazing behavior across the substrate and rockwork specifically to consume these primary producers. While they do consume other organisms like LPS corals, fanworms, and tunicates, the steady grazing on algae forms the core basis of their nutritional intake in the wild, which directly influences the need for high-quality vegetable matter supplementation in captivity.
