Melanotaeniidae (Rainbowfishes, blue eyes)
Etymology: Melanotaenia: Greek, melan, -anos = black + latin, taenia = stripe (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生态学
; 淡水 底中水层性. 热带
Oceania: Australia. Formerly identified as M. australis, but DNA studies indicate otherwise; the two species' geographic ranges do not overlap.
大洋洲: 澳洲。 从前鉴定为 M. 南极光 了，但是染色体研究不一样地指出; 两者正币的地理范围不重迭。

背棘 (总数) : 5 - 7; 背的软条 (总数) : 9 - 12; 臀棘: 1; 臀鳍软条: 18 - 21. Scales: horizontal rows 10-13; vertical rows 31-36; predorsal 14-22; cheek 9-13. Greatest body depth (>5 cm SL), females 30.5-36.2 and males 32.9-41% of SL (Ref. 44894).
鳞片: 水平的列 10-13; 垂直的列 31-36; 前背的 14-22; 颊的 9-13. 最大的体高 (>5 公分 SL) ，雌性 30.5-36.2 与雄性 32.9-41% 的 SL.(参考文献 44894)
Habitat where found is highly variable, including rivers, creeks, swamps, marshy lagoons, lakes, and reservoirs. Usually forms aggregations at or near the surface of deeper pools in stream habitats, especially where there is aquatic vegetation or log debris (Ref. 44894).
栖息地在哪里发现是高变异的，包括河，小溪，沼泽，多沼地的舄湖，湖与水库。 通常聚集成群在或者在水流栖息地的较深的水池的接近水表面, 尤其在哪里有水生植物或废弃圆木.(参考文献 44894)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
