Etymology: Melanotaenia: Greek, melan, -anos = black + latin, taenia = stripe (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 7.0 - 7.4. Tropical; 23°C - 27°C (Ref. 44894)
Oceania: originally known only from Lake Eacham, a circular crater lake situated on the Atherton Tableland in northern Queensland, Australia. Recently recorded at widespread localities on the Tablelands between the Barron and South Johnstone river systems.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 3 - ? cm
Max length : 6.5 cm SL male/unsexed; (Ref. 5259)
Inhabits small creeks and crater lakes where it congregates along the shallow edges among aquatic vegetation (Ref. 44894). Often found among aquatic vegetation, fallen logs or branches (Ref. 11236). Occurs at temperature and pH ranging from 23-27° C and 7.0-7.4 respectively (Ref. 44894).
Distinct pairing (Ref. 205).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 206).
Vulnerability (Ref. 59153
