小三角波鱼
Trigonostigma hengeli, perhaps better known as the Glowlight Rasbora or Hengel’s Rasbora, is native to Borneo and Sumatra, Indonesia. It has been collected from Sumatra’s Jambi province and from the Tambesi River. It is usually found in gentle streams and densely vegetated tributaries. Trigonostigma hengeli can reach a length of 3 cm in an aquarium. This species has a small, translucent body and a slim, bright orange line extending laterally. There is a black marking below the orange line; the orange and black become more intense when the fish is in good health. This species is difficult to sex, but adult females are generally larger with a rounded belly.

体型、体态和金三角很相似,只是小了一号,不过体色并没有那么红,反倒是透明感十足。一度水族提示,本种喜欢弱酸性的软水,性情温和,容易饲养,可喂食人工饵料,体长可达3公分。
