Description
Castelnau's Wrasse is a moderately sized saltwater fish from the Indo-Pacific, recognized by its distinctive sail-like dorsal fin and mottled camouflage. This benthic hunter sifts through sand for small invertebrates, making it an interesting addition to a mature reef or fish-only aquarium. It can be territorial, especially towards other wrasses.
