Max length : 4.8 cm SL male/unsexed; (Ref. 44894 ); common length : 3.0 cm SL male/unsexed; (Ref. 5259 ); max. reported age: 1.00 years (Ref. 44894 )

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274 ); Frequently found among vegetation along the edge of still or slow-running waters like swamps, drainage ditches and backwaters of creeks. Adults live in both ephemeral and permanent habitats. A short-lived fish, reaching maturity in the first year of life and perishing shortly after spawning. Fish occupying ephemeral water possibly aestivate or shelter in crayfish burrows when surface water evaporates during summer (Ref. 44894 ). Probably an annual species. Spawn from July to October. Like its southwestern relative G. munda , this species is also a multiple spawner (Ref. 44894 ). Females deposit a few eggs per day on leaf litter. Eggs hatch after 10-17 days at 16°-21°C. Scanty information on diet: captive specimens eat small invertebrates and filamentous algae.

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.2   ±0.32 se; based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=1;tm=1;Fec=66). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
