One of the most colorful species of the genus, especially during its reproductive period. Frequently occurs in zones with little current and over a substrate covered with vegetal debris (Ref. 27188). Caught frequently but not abundantly in most varied biotopes- in small creeks and flooded zones with clear, shallow and slow flowing water. Feeds primarily on insects, secondarily on fishes and plants. Very territorial. During reproduction, males attain a deeper coloration. About 1,000 eggs are released during spawning. Spawning takes place on stone or wood. Parents take care of juveniles (Ref. 35237). Maximum length 25 cm TL (Ref. 1672).
本属的最色彩鲜艳种之一, 尤其在它的生殖的时期时。 时常出现于中有少的水流的地方而且在一个底部之上覆盖着植物的残枝.(参考文献 27188) 时常捕捉了但是不大量地在大多数的不同生存环境中- 在小溪中与被水淹没的有清澈的, 水浅的与缓慢流动的水的地方。 主要吃昆虫, 在第二在鱼与植物上。 非常具有领域性。 在繁殖的时候，雄性达到一个较深的颜色。 大约 1,000个卵在产卵的时候被释放。 产卵在石头或木材上发生。 亲鱼照顾稚鱼。 (参考文献 35237) 最大的长度 25 公分TL.(参考文献 1672)
