The Yellow Belly Blue Tang, scientifically known as Paracanthurus hepatus, is a color variant of the popular Blue Tang, notable for its striking blue body and a yellow belly and tail. This variant also features a distinctive black marking on its upper body that forms a sort of "palette" design.
Key characteristics of the Yellow Belly Blue Tang:
Coloration: A vibrant blue body with a bright yellow tail and belly.
Markings: A black marking, shaped like a horizontal bar, extends from the back of the head, loops around the gills, and then extends back to the base of the tail.
Size: Can grow up to 8-12 inches (20-30 cm) in length.
Temperament: Generally peaceful but can become territorial and aggressive towards other tangs, especially when they mature.
Reef Compatibility: Reef safe, meaning they don't typically harm corals or other invertebrates.
Diet: Herbivorous, primarily consuming algae and marine plants.
Habitat: Found in coral reefs of the Indo-Pacific region.
Additional details:
The yellow coloration on the belly and tail is most prominent in adults, though even small juveniles may show some yellowing.
They are known for their active swimming and need a spacious aquarium with plenty of swimming room.
They are susceptible to certain diseases, particularly Ich, so maintaining good water quality and a healthy diet is crucial.
Their sharp tail spine (scalpel) is used for defense and can inflict a painful wound.
They require a varied diet, including algae-based foods, to maintain their health and reduce aggression.
The Amphiprion percula, commonly known as the orange clownfish or percula clownfish, is a small, brightly colored marine fish characterized by its orange body and three distinctive white bands outlined in black. These bands are located behind the eyes, in the middle of the body (often with a forward-bulging section), and near the tail. The fins are also edged with black. They are often confused with the similar-looking Amphiprion ocellaris, but can be distinguished by the number of dorsal fin spines (10 in A. percula vs. 11 in A. ocellaris) and the thickness of the black outlining on the white bands.
Key Characteristics:
Coloration: Bright orange body with three white bands edged in black.
Bands: The first band is behind the eyes, the second in the middle of the body, and the third near the tail.
Size: Can grow up to 11 cm (4.3 inches) in length.
Dorsal Fin Spines: Typically 10.
Symbiotic Relationship: Lives in a symbiotic relationship with sea anemones, providing protection and receiving a safe habitat.
Social Structure: Organized in size-based hierarchies within anemones.
Sexual Dimorphism: Females are larger than males.
The ocellaris clownfish, or Amphiprion ocellaris, is a vibrant marine fish known for its striking orange body, three white bands, and black outlines. These fish, also called false percula clownfish or common clownfish, form a symbiotic relationship with sea anemones, using their mucus-covered skin to avoid being stung by the anemone's tentacles.
Physical Characteristics:
Color: Primarily bright orange with three distinct white bands.
Bands: The white bands are usually outlined in black. The middle band often has a rounded bulge in the middle.
Size: Typically grow to about 3-5 inches (8-11 cm) in length.
Fins: Black markings on the fins, particularly the dorsal fin, are common.
Other Notable Features:
Symbiotic Relationship:
They have a mutually beneficial relationship with sea anemones, living among their tentacles for protection from predators.
Protective Mucus:
A special layer of mucus on their skin protects them from the anemone's stinging cells.
Protandrous Hermaphrodites:
All begin life as males and can change to females as they mature, with the largest fish in a group typically being female.
Regional Variations:
While typically orange, some can be darker red-orange or even black with white bands, depending on their location.

Acanthurus olivaceus, the orange-band surgeonfish, the orange-shoulder surgeonfish or the orangebar tang,is a species of marine ray-finned fish belonging to the family Acanthuridae, this family includes the surgeonfishes, unicornfishes and tangs. It lives in the tropical waters of the Indo-west Pacific.
Taxonomy
Acanthurus olivaceus was first formally described in 1801 by the German naturalists Marcus Elieser Bloch and Johann Gottlob Theaenus Schneider with its type locality given as Tahiti in the Society Islands,This species is closely related to the range restricted Marquesas surgeonfish (A. reversus), and together these taxa form a species complex within the genus Acanthurus.The genus Acanthurus is one of two genera in the tribe Acanthurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamilies in the family Acanthuridae.
Description
The orange band surgeonfish is a deep-bodied, laterally-compressed oval fish, rather over twice as long as it is deep, with a maximum length of 35 cm (14 in), although a more typical length is 25 cm (10 in). Both dorsal and anal fins are long and low, extending as far as the caudal peduncle. The dorsal fin has nine spines and 23 to 25 soft rays while the anal fin has three spines and 22 to 24 soft rays. The tail fin is crescent-shaped, the points growing longer as the fish gets older. The adult fish is greyish-brown; a sharp vertical line usually separates the paler front half of the fish from the darker hind portion. There is a distinctive orange bar, surrounded by a purplish-black margin, immediately behind the top of the gill cover, and blue and orange lines at the bases of the fins. Like all surgeonfish, this species has a pair of scalpel-like scales that project upward from the caudal peduncle. Larger males develop a convex snout which clearly differentiates them from females. Juvenile fish are yellow.
Distribution and habitat
This fish is found in the tropical eastern Indian Ocean and the western Pacific Ocean. Its range extends from Christmas Island and the Cocos Keeling Islands to southern Japan, Western, Northern and Eastern Australia, Indonesia, the Philippines and Hawaii. It is associated with reefs, often on outer slopes and in more exposed locations. As an adult, it is a solitary fish or sometimes joins schools, with a depth range of between about 9 and 46 m (30 and 150 ft), but juveniles are found in shallower water in sheltered locations in small groups.
Ecology
The orange band surgeonfish feeds on detritus and on algae growing on the seabed, as well as the film of diatoms and filamentous algae that grows on sand and other substrates.[2] It often forms schools with parrotfish, tangs and other species of surgeonfish, which all have similar diets; their grazing is important in maintaining biodiversity by keeping rocks free from excessive growth of algae so that coral larvae can find suitable habitat to settle. The fish can change colour from dark to pale almost instantaneously.
Status
The orange band surgeonfish has a wide distribution in the tropical Indo-Pacific region and is moderately common. It is sometimes found in fish markets and in the aquarium trade but is not a species targeted by fisheries. No particular threats have been recognised, so the International Union for Conservation of Nature has listed its conservation status as being of least concern.
The red-eye wrasse (Cirrhilabrus solorensis) is a species of wrasse native to Indonesia and Australia, where found near the Lesser Sundas, Maluka and Darwin. It inhabits coral reefs on coastal and outer reef lagoons at depths of 5 to 35 m (16 to 115 ft).
Adult male C. solorensis have a yellowish-dusky or yellow-green snout to crown, blue operculum, purple neck-region, yellow-orange upper body and blue belly. It can reach a total length of 11 cm (4.3 in).Until 2021, it was commonly confused with C. aquamarinus and C. chaliasi, which occur in similar habitats and all have mostly reddish eyes. In C. aquamarinus, which is found near Sulawesi, the adult male has a mostly deep yellow head, a dark blue back and operculum, and much of the body is blue-green. In C. chaliasi, which is found near the Lesser Sundas and Tukangbesi Islands, the adult male has a pinkish-red head, yellow-orange upper body and blue belly.Females of these species are considerably duller and not as easily separated.
C. solorensis occurs in small harems of one male, several females and juveniles. It is regarded as data deficient by the IUCN. It can be found in the aquarium trade.
