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。 出現在平靜的沿岸水域;(參考文獻 27188) 在滿佈植物的沼澤中。 捕食蠕蟲，小型甲殼動物與昆蟲。 (參考文獻 7020) 在水族館之中很受歡迎由於他們的結實，和平的特徵與嬌弱的顏色.(參考文獻 12225) 繁殖是容易地成功完成,300 到 400個卵被獲得每產卵.(參考文獻 27188) 水族館保持: 形成 5個或更多個體的群體; 水族館最小體型 60 公分.(參考文獻 51539)
