Humeral spot round and small, about the size of the pupil; the dorsal fin black spot is over lined with white and underlined with yellow, color patterns of pelvic and anal fins are symmetrical; adipose fin is hyaline (Ref. 12225).

Gregarious and non-aggressive. Occur in calm coastal waters (Ref. 27188); in densely vegetated swamps. Feed on worms, small crustaceans and insects (Ref. 7020). Are popular among aquarists because of their robustness, peaceful character, and delicate colors (Ref. 12225). Reproduction is easily carried out, 300 to 400 eggs are obtained per spawn (Ref. 27188). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).
群居而非侵略性。 出现在平静的沿岸水域;(参考文献 27188) 在满布植物的沼泽中。 捕食蠕虫，小型甲壳动物与昆虫。 (参考文献 7020) 在水族馆之中很受欢迎由于他们的结实，和平的特徵与娇弱的颜色.(参考文献 12225) 繁殖是容易地成功完成,300 到 400个卵被获得每产卵.(参考文献 27188) 水族馆保持: 形成 5个或更多个体的群体; 水族馆最小体型 60 公分.(参考文献 51539)
