Pseudomonacanthus peroni is a marine fish from the Monacanthidae family. It lives in warm coastal waters and can change its body color for camouflage.
This species is distinguished by its ability to quickly change body color depending on the background. It is important for nature because it helps control the growth of algae on coral reefs.
Immature form that undergoes metamorphosis before adulthood.
