Maturity: L_m ? range ? - ? cm
Max length : 10.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 7020); common length : 6.0 cm SL αρσενικό/απροσδιόριστο; (Ref. 44894)

Inhabits rainforest streams, lily lagoons and small streams. Also occurs in larger streams, usually in backwaters or along the shoreline where there is minimal flow and grassy vegetation. Often found in brackish coastal waters (Ref. 7020, 44894). Temperature and pH ranges are 23°-28°C and 5.5-7, respectively (Ref. 44894). Feeds mainly on aquatic and terrestrial insects and their larvae, and also filamentous green algae. Usually co-occurs with other species of rainbows and blue-blue eyes. A popular aquarium species which thrives in captivity. Type species (first species to be described) of the family Melanotaeniidae (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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).

Τροφικό Επίπεδο (Ref. 69278): 2.9 ±0.35 se; based on food items.

Ελαστικότητα (Ref. 120179): Μεσαίο(α), ελάχιστος χρόνος για διπλασιασμό πληθυσμού 1,4 - 4,4 έτη (Spawns throughout the year (Ref. 5259)).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
