Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 13337)

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7-9; Anal spines: 2-3; Anal soft rays: 16 - 19. Can be easily confused with Micralestes acutidens but has a more slender body with no black tip to the dorsal fin. Does not possess a pair of conical teeth behind row of teeth in lower jaw as in M. acutidens.

Biology     Glossary (e.g. epibenthic)

Shoals in shallow, vegetated marginal and floodplain habitats. Appears to prefer a swampy environment to open water (Ref. 13337). Feeds on small aquatic insects and other invertebrates. A partial spawner, breeding during high-water periods (Ref. 7248). Known to migrate up rivers and on to floodplains during flood season (Ref. 13337).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.39 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
