Cirrhilabrus aurantidorsalis is a compact fairy wrasse endemic to Indonesia, restricted to the Togean Islands and the adjacent Tomini Bay shores of Sulawesi. Males carry a vivid yellow-to-orange back that contrasts against a magenta to purple lateral region, finished with a dark-red crown-like marking across the head. Females are considerably more subdued, showing reddish brown tones with a pale lower face and belly. Adults reach roughly 4 inches, and male coloration shifts noticeably with mood, reaching peak saturation during courtship displays.

In the wild this species forms small groups along reef edges bordered by rubble patches, typically between 10 and 25 meters. Aquarium housing should echo that structure: plan on a 50-gallon or larger system with open swimming lanes above an aquascape that offers numerous crevices and caves. This wrasse does not bury itself in sand overnight, instead wedging into rockwork or forming a mucus cocoon, so reliable shelter matters. A tightly fitting canopy or comparable secure cover is essential, since fairy wrasses are strong jumpers. Freshly introduced fish frequently stay hidden for several days before they settle in and begin using the open water column.
