Tiger barb
The tiger barb or Sumatra barb (Puntigrus tetrazona), 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. 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, which are similar in appearance.

The tiger barb can grow to about 7ÔÇô10 centimeters (2.8ÔÇô3.9 inches) long and 3ÔÇô4 centimeters (1.2ÔÇô1.6 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.

In the aquarium
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. 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. 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. 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. 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).

Breeding
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.
