The Orangeback fairy-wrasse (Cirrhilabrus aurantidorsalis) is a small, colorful fish known for its vibrant orange back, which contrasts with a magenta stripe along its body and a shimmering belly. Males are more intensely colored, especially during courtship, and have a dark red "crown" marking. They inhabit coral reefs in the Indo-Pacific, live in small groups with one male and several females, and are popular in the aquarium trade for their peaceful nature and activity level.  Appearance Coloration:  Has a brilliant orange or golden-orange back, a magenta stripe running the length of the body, and a belly that can be pink, blue, or purple.  Male features:  Males have more intense colors and a dark red crown-like marking on the head. During courtship, their colors intensify significantly.  Female features:  Females are less vibrant, with a reddish-brown body, white face, and white belly.  Body shape:  Slender and elongated body.  Habitat and behavior Habitat:  Found in the Indo-Pacific, specifically in the eastern Tomini Bay and Lembeh Strait, on reef slopes and edges with rubble areas.  Social structure:  Lives in small groups (harems) consisting of one male and several females. All are believed to start as females, with some transforming into males.  Temperament:  Peaceful and active fish, making them suitable for reef aquariums. They are reef-safe and will not harm corals or invertebrates.  Jumping:  Known to be good jumpers, so a tight-fitting lid on the aquarium is essential.  Diet Primary food: Zooplankton.  Aquarium diet: Readily accepts a variety of meaty foods, such as frozen mysis shrimp, brine shrimp, and other high-quality flakes, pellets, and frozen/live foods.

The Acanthurus pyroferus, or mimic surgeonfish, is a species that shows distinct differences between juveniles and adults. Juveniles are bright yellow with blue highlights, mimicking angelfish, while adults are typically dark brown to purplish-black with a yellowish-tan front. Both have an orange patch at the gill opening, a distinctive defense spine on the tail, and reach up to 29 cm in length.  Juvenile appearance Body: Oval-shaped and bright yellow. Highlights: Blue highlights around the eyes and gill covers. Mimicry: They mimic species like the Lemonpeel Angelfish (Centropyge flavissimus).  Adult appearance Body: Disk-shaped and can range from yellowish-tan to purplish-black.  Coloration: Often a chocolate brown with a grayish head.  Highlights: Red-orange highlights around the eyes and pectoral fins.  Gill opening: A distinct orange patch is present at the gill opening.  Caudal fin: Has a white posterior margin.  Other characteristics Size: Adults can reach up to 29 cm (11 inches) in length.  Fins: The dorsal fin has 8 spines and 27-30 soft rays; the anal fin has 3 spines and 24-28 soft rays.  Tail spine: Like other surgeonfish, they have a pair of sharp, depressible spines on either side of their tail base for defense.  Habitat: Found in the Indo-Pacific region, inhabiting mixed coral, rock, and sand areas of reefs.  Diet: They are herbivores that primarily feed on algae.
