(Puntius tetrazona)
Tiger barbs are very active schooling fish, which need at least 8 in a group and a 25 gallon tank; with less tigers, they will be more likely to be aggressive towards any tankmates. They get along well with other fish if the others are not slow moving and do not have long fins. They need to have room for swimming, some hiding spots, and plants. They get along great with bottom feeders and top-dwellers as long as they have short fins. Other fish in the middle of the water column are usually chased around.
Tiger barbs come from Southeast Asia; they're native to Indonesia and Malaysia. They are usually found in clear, medium fast streams in the tropics. Some have also been found in swampy lakes where the water quality changes a lot; they're very hardy fish, which is great for beginners.
Sexing tiger barbs is not difficult. The male has dark orange on his face and bright red on the edge of his dorsal fin. Females have less red and are usually fatter. They're pretty easy to breed, but they eat their own eggs so a separate spawning tank is necessary if you want to raise fry.
Tiger barbs are very adaptable to most aquarium parameters. They thrive in soft, slightly acidic water with a pH between 6 to 7 and dH between 4 to 10. They can tolerate any pH from 5-8.5 and dH between 4-19. An ideal temperature for them in the aquarium is around 74-79F (23-26C). For breeding purposes, the pH is best just around 6 with a temperature of 81F (27C).
Tigers grow to about 3 inches; they grow very quickly if fed on frozen or live foods. They accept flake foods and even eat algae wafers. They also like to munch on fresh cucumber and zucchini.
Tiger barbs are very pretty; gold color with bold stripes and red markings. The black parts sometimes have an iridescent green shine. They come in three main color variations; there's natural gold and black, green, and albino. There are also a few other colors, like platinum and black, but they're based off the green and are pretty hard to find. Since all of them are still the same species, they shoal together, giving options as to which colors you would like in your aquarium.
