Max length : 14.0 cm TL male/unsexed; (Ref. 5638)

Biology     Glossary (e.g. epibenthic)

Adults inhabit lakes, often solitary (Ref. 86760). Feed mainly on shrimps (Ref. 30769). Females brood their young in the mouth (Ref. 86760).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs from the cleavage phase and larvae of up to 0.89 cm TL are mouthbrooded by male and female parents ranging from 6.7 to 7.0 cm SL (Ref. 86760).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00693 - 0.03157), b=2.97 (2.80 - 3.14), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
