Inhabits steep gradient streams with numerous cascades and normally crystal clear water. Tends to congregate in pools at the base of small waterfalls where flow is rapid but is also found in quieter sections of streams and lakes. Prefers areas fully exposed to sunlight. Found in small, clear, swift-flowing streams, occasionally seen above high waterfalls. Also occurs in a lacustrine environment at the base of Edith Falls (Northern Territory) (Ref. 44894). Feeds mainly on aquatic and terrestrial insects and their larvae, also on green algae. Sympatric with M. splendida australis. A good aquarium fish, typical of most rainbowfishes in this respect. Should probably be provided with more space and additional aeration than is usually recommended for fish of this size due to its fast swimming habits and affinity for well-oxygenated waters at the base of waterfalls and rapids (Ref. 44894).
栖息于陡峭的溪流有很多的小瀑布与通常清澈透明的水域。 倾向在水流是迅速的小瀑布的基底的水池中聚集但是也被发现于溪流与湖的较安静的部分。 偏爱区域充分暴露于日光。 发现于小且清澈又快速流动的溪流了,偶然地见到上方高的瀑布。 在伊迪丝秋天 (北部地区) 的基底也生活于湖泊的环境中。 (参考文献 44894) 主要吃水生而陆栖的昆虫与他们的幼体, 也吃绿藻。 与 M. splendida australis 重迭分布了。 一个好水族馆鱼, 典型的这敬意的大多数彩虹鱼。 可能应该被提供比通常是為這一個大小的魚推薦有更空間與附加的透氣在瀑布與急流的基底為溶氧量高的水域由於它的快速游泳習慣與分類相關.(參考文獻 44894)
