Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 44894); common length : 9.0 cm SL male/unsexed; (Ref. 5259); max. reported age: 6 years (Ref. 6994)

Occur in coastal streams, lakes and ponds. Inhabit clear or darkly tannin-stained water of rivers, streams, swamps and lakes, usually near the cover of rocks, aquatic plants or woody debris (Ref. 44894). Cryptic during the day under stones or among vegetation, but actively feeding at night on various crustaceans, small fishes, aquatic insects and gastropods (Ref. 44894). Migrate to spawn in small side creeks after winter rains (August and September) (Ref. 6994). Males reach maturity after their first year, female after their second (Ref. 6994). Maximum life span is about six years (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [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).

Trophic level (Ref. 69278): 3.3 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=6; tm=1; K=0.67; Fec=230).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
