The tiger barb or Sumatra barb (Puntigrus tetrazona), [2] is a species of tropical cyprinid fish. The natural geographic range reportedly extends throughout the Malay Peninsula, Sumatra and Borneo in Indonesia, with unsubstantiated sightings reported in Cambodia. [3] Tiger barbs are also found in many other parts of Asia, and with little reliable collection data over long periods of time, definite conclusions about their natural geographic range versus established introductions are difficult. Tiger barbs may sometimes be confused with Puntigrus anchisporus , Puntigrus navjotsodhii, or Puntigrus partipentazona, which are similar in appearance, the only differences being the slightly different stripe pattern and the number of scales these fish have. [4]



The tiger barb can grow to about 7–10 centimeters (2.8–3.9 inches) long and 3–4 centimeters (1.2–1.6 inches) wide, although they are often smaller when kept in captivity. Some can grow to around 13 centimeters as well. Native fish are silver to brownish yellow with four vertical black stripes and red fins and snout. The green tiger barb is the same size and has the same nature as the normal barb, but has a green body. The green tiger barb, often called the moss green tiger barb, can vary considerably in how green it looks; to some people, it looks nearly black. Albino barbs are a light yellow with four barely visible stripes.


Tiger barbs have been reported to be found in clear or turbid shallow waters of moderately flowing streams. They live in Indonesia, Borneo, tropical climates and prefer water with a 6.08.0 pH, a water hardness of 519 dGH, and a temperature range of 77 - 82 °F or 25 - 27.8 °C. Their discovery in swamp lakes subject to great changes in water level suggests a wide tolerance to water quality fluctuations. Their average lifespan is 7 years. When exposed to decreased temperature levels, the Tiger barb fish experiences a change in body color. The male fish tend to display a bright red color in the dorsal fin, ventral fin, caudal fin, and snout. When the water temperature drops to 21 °C, both the male and the female fish were observed to have a decayed body color. When the temperature decreases even further to 19 °C, their distinct stripes even appear to be dimmed.

Commercial importance

The tiger barb is one of over 70 species of barb with commercial importance in the aquarium trade. Of the total ornamental fish species imported into the United States in 1992, only 20 species account for more than 60% of the total number of specimens reported, with tiger barbs falling at tenth on the list, with 2.6 million individuals imported. (Chapman et al. 1994). Barbs that have been selectively bred to emphasize bright color combinations have grown in popularity and production over the last 20 years.[ when? ] Examples of colour morphs (not hybrids) of tiger barb include highly melanistic green tiger barbs that reflect green over their black because of the Tyndall effect, gold tiger barbs and albino tiger barbs.

The tiger barb, an active shoaling fish, is usually kept in groups of six or more. They are often aggressive in numbers less than five, and are known fin nippers. [5] [6] Semi aggressive fish form a pecking order in the pack which they may extend to other fish, giving them a reputation for nipping at the fins of other fish, especially if they are wounded or injured. They are thus not recommended for tanks with slower, more peaceful fishes such as bettas, gouramis, angelfish and others with long, flowing fins. [5] They do, however, work well with many fast-moving fish such as danios, platys and most catfish. When in large enough groups, however, they tend to spend most of their time chasing each other and leave other species of fish alone. [7] They dwell primarily at the water's mid-level. One of the best tankmates for the tiger barb provided there is considerable space is the clown loach, which will school with the tiger barbs and act as they do, and the tigers act as the loaches do. Tiger barbs do best in soft, slightly acidic water. [5] The tank should be well lit with ample vegetation, about two-thirds of the tank space. These barbs are omnivorous, and will consume processed foods such as flakes and crisps, as well as live foods. They are relatively greedy with their food consumption and can become aggressive during feeding time. Tiger barbs seem more susceptible than other species to cottonmouth (columnaris), a bacterial infection.

The tiger barb was also used to make genetically modified fish sold as GloFish (fluorescent colored fish).

The tiger barb usually attains sexual maturity at a body length of 2 to 3 centimeters (0.79 to 1.18 inches) in total length, or at approximately six to seven weeks of age. The females are larger with a rounder belly and a mainly black dorsal fin, while the males have a bright, red nose with a distinct red line above the black on their dorsal fins. The egg-layers tend to spawn several hundred eggs in the early morning in clumps of plants. On average, 300 eggs can be expected from each spawn in a mature broodstock population, although the number of eggs released will increase with the maturity and size of the fish. Spawned eggs are adhesive, negatively buoyant in freshwater and average 1.18 ± 0.05 mm in diameter.

Tiger barbs have been documented to spawn as many as 500 eggs per female (Scheurmann 1990; Axelrod 1992). Females can spawn at approximately two week intervals (Munro et al. 1990).

Once spawning is finished, they will usually eat any of the eggs they can find.

Common hybrids

Interspecific and intraspecific hybridization is done to achieve different colors and patterns to satisfy market demand for new tiger barb varieties. Gold and albino tiger barbs are examples of commercially produced fish based on recessive xanthic (yellow) and albino genes. These are not hybrids.

<i>Pterophyllum</i> Genus of fish

Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as angelfish. All Pterophyllum species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped transversely, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All Pterophyllum species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed.

Other fins are silver to transparent. The glowlight tetra is a peaceful, shoaling fish. It is larger than the neon tetra, and its peaceful disposition makes it an ideal, and popular, community tank fish. It should be kept with similar sized, non-aggressive species. Hemigrammus gracilis is a senior synonym. The red-line rasbora of Malaysia and Indonesia has markings and coloring very similar to H. erythrozonus, but is a member of family Cyprinidae, not a close relative.

It was believed to be extinct for over 20 years in 1980, but an apparently native population of this fish was discovered on Hainan Island, well away from the White Cloud Mountain. They are bred in farms and are easily available through the aquarium trade. However, inbreeding in farms has led to genetically weak stock that is vulnerable to disease and prone to physical deformities.
