Platax pinnatus, also known as the pinnate batfish, dusky batfish, shaded batfish, or red-faced batfish is a fish from the western Pacific that occasionally is kept in marine aquariums.

Anatomy and morphology[edit]

As a juvenile it is brown with orange stripe outlining its entire body. Adults become a dull silver. This fish grows to a maximum size of 45 cm (18 in).

Importance to humans[edit]

In captivity[edit]

This is almost always a poor choice of fish for an aquarium. They are poor shippers, and typically die within the first few days in the aquarium. Even compared to other batfish they are known for being fragile. Those few that do survive lose their juvenile coloration and exhibit an adult color form typically considered less attractive.

In the wild[edit]

Platax pinnatus has been observed to significantly reduce algal growths on coral in studies simulating overfishing on the Great Barrier Reef.[1]
