The pentazona barb (Puntius pentazona), or fiveband barb is a tropical fish belonging to the Barb genus of the minnow family. It is a native of Southeast Asia, including Cambodia, Indonesia, Malaysia, Singapore, and Vietnam. 
The fish superficially resembles the tiger barb, except that there are five black vertical bands on an orange or gold body instead of four bands on the tiger barb. The fish will grow to a maximum length of 2 in (5 cm).
The fish lives natively in calm tropical waters in the lowlands in water with a 5–7 pH, a water hardness of 2–13.0 dGH, and a temperature range of 24–28 °C
The fish has commercial importance in the aquarium hobby and is frequently inaccurately referrered to as a tiger barb (Puntius tetrazona).
Pentazona barbs are egg-scatterers that spawn among a course gravel bed in open water. Once spawning is finished, they will usually eat any of the approximately 200 eggs that they find. It is usually necessary to separate the fish from the eggs after spawning in order to prevent the eggs from being eaten. The eggs will hatch in approximately 1 day.

The pentazona barb is a harmless, active schooling fish that is usually kept in groups of 5 or more. They prefer a well planted environment with rocks and driftwood but still need plenty of space to school.

原产地为亚洲南部的马来半岛及婆罗洲。种名为“pentazona”,即是拉丁文的五带之意,而英名亦称之为“Five - Banded”,意亦为五带。实际上是如此,体型与体色,乍看之下常被误认为Tiger Barb,但本种即因体侧有五条黑带,故称之为“五间鱼”,可作为分别。适水温为24 - 28,喜好弱酸性到中性的软水。性情活泼温驯,能与同体型的其他小型鱼混合饲养。。
