Biologia     Glossario (es. epibenthic)

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).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.34 se; based on food items.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100) .
