A true gem for serious reef keepers, the Yurple Tang is an exceptionally rare find. Experience the pinnacle of marine ornamental aquaculture with the Yurple Tang, an ultra-rare hybrid exclusively bred by Bali Aquarich, the world’s leading marine fish breeder. This stunning fish, a cross between the Yellow Tang (Zebrasoma flavescens) and Purple Tang (Zebrasoma xanthurum), showcases a mesmerizing blend of deep purples and vibrant yellows.

While natural Zebrasoma hybrids do sometimes occur in the wild where their habitats overlap (like near Hawaii or the Red Sea), a consistent, captive-bred hybrid is exceedingly rare and difficult to achieve.

• Genetic Advantage: By being aquacultured (tank-raised), the Yurple Tang possesses an advantage over wild-caught specimens. It is already accustomed to prepared aquarium foods and is far less stressed during shipping and acclimation, leading to better long-term survival and health in your home reef.

• Color Transition: New owners should watch for subtle, exciting color changes. Like its parent species, the Yurple Tang’s color may deepen or change in intensity based on its mood, lighting, and health. The blend of xanthic (yellow) and purple pigments creates a dynamic hue that constantly catches the eye.

The Vampire Tang (Acanthurus tennentii) is a bold and active surgeonfish named for the small “fang-like” markings near its mouth. Known for its striking grayish-blue body, yellow dorsal highlights, and dark facial band, this tang adds a unique presence to large reef aquariums. Despite its common name, it’s a peaceful grazer most of the time, though it can become territorial toward other tangs, especially those with similar body shapes.

The Chocolate Tang (Acanthurus pyroferus) is a beautiful and fascinating species known for its ability to mimic angelfish as a juvenile — often resembling Centropyge species like the Lemonpeel or Herald’s Angelfish. As it matures, it transitions to a rich brown or “chocolate” coloration with striking orange and blue highlights near the pectoral fins and tail base.

Active, intelligent, and constantly grazing, this tang brings both movement and color to large reef systems. While mostly peaceful, it can be territorial toward other tangs, especially those from the Acanthurus genus.

The Yellow Belly Hippo Tang is a stunning regional variation of the classic Paracanthurus hepatus, easily identified by its brilliant blue body, black markings, and vibrant yellow belly and tail. This variant is native to the Indian Ocean and is prized by collectors for its deeper coloration and unique contrast compared to the Pacific Blue Tang.

Playful, intelligent, and constantly active, this tang spends its day grazing on algae and darting around open swimming areas. Like all surgeonfish, it has sharp spines (“scalpels”) near the tail used for defense — handle with care.

The White Tail Kole Tang, *Ctenochaetus strigosus*, is a popular and attractive surgeonfish known for its vibrant coloration and active nature. Its body is typically a rich brown to reddish-brown, adorned with numerous fine, horizontal blue lines that cover the head and body. A distinctive feature is its bright white tail, which provides a striking contrast to its darker body. The eyes are often ringed with yellow.

A minimum tank size of 75 gallons is recommended for the White Tail Kole Tang to provide ample swimming space and grazing opportunities. They are considered an intermediate-level fish, requiring a mature aquarium with plenty of live rock for grazing on algae. While generally peaceful towards other fish, they can be territorial with other tangs, especially those of similar shape or size. Introducing them as one of the last fish in the tank can help minimize aggression.

In the aquarium, the White Tail Kole Tang is an excellent algae grazer and will spend much of its time picking at the rockwork. Their diet should be supplemented with a variety of marine-based foods, including high-quality marine flake and pellet foods, dried seaweed (nori) offered on a veggie clip, and frozen mysis shrimp or brine shrimp. A varied diet is crucial for their health and to prevent nutritional deficiencies. They typically reach a maximum size of around 7 inches in captivity. Like other tangs, they are susceptible to marine ich, so maintaining excellent water quality is essential.

The Atlantic Blue Tang, *Acanthurus coeruleus*, is a stunning and highly recognizable surgeonfish native to the coral reefs of the Atlantic Ocean. Its vibrant, electric blue coloration is a true showstopper, making it a prized addition to many marine aquariums. As juveniles, they are typically bright yellow, transitioning to blue as they mature.

A minimum tank size of 180 gallons is recommended for the Atlantic Blue Tang due to its active swimming nature and potential adult size. This species requires a well-established aquarium with plenty of live rock for grazing and hiding. They are herbivores and will spend their day picking at algae on the rockwork. While generally peaceful towards other fish, they can be territorial towards other tangs, especially those of similar size and shape.

The Atlantic Blue Tang is considered an advanced care level fish. They are susceptible to marine ich and require excellent water quality and a varied diet to thrive. Their diet should consist primarily of marine algae, offered through dried seaweed sheets, spirulina flakes, and high-quality herbivore pellets. Supplementing with occasional meaty foods is also beneficial. They can reach a maximum size of around 15 inches in captivity.

The Achilles Tang (Acanthurus achilles) is a strikingly bold surgeonfish whose velvety black body and vivid orange teardrop marking near the tail captivate advanced marine hobbyists. Native to surge‑swept Pacific reefs—especially around Polynesia, Micronesia, and Hawaii—this species is highly active and constantly grazing, requiring excellent flow, oxygenation, and pristine water. Its territorial behavior and sensitivity to stressful conditions make it a challenging but rewarding centerpiece in a large, mature reef system. Achilles tangs are fully reef‑safe but demand precise husbandry; they should only be considered by aquarists experienced with tangs and surge‑zone species.
