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).
棲息於陡峭的溪流有很多的小瀑布與通常清澈透明的水域。 傾向在水流是迅速的小瀑布的基底的水池中聚集但是也被發現於溪流與湖的較安靜的部分。 偏愛區域充分暴露於日光。 主要吃水生而陸棲的昆蟲與他們的幼體, 也吃綠藻。 與 M. splendida australis 重疊分佈了。
