Maturity: Lm ?  range ? - ? cm
Max length : 11.2 cm TL male/unsexed; (Ref. 5684)
This fish is a cave-dweller. The male actively digs under the rocks in the lake to build a secret nesting place. The female enters and leaves with a mouthful of eggs. They brood for 25 days; the eggs hatch in less than a week (Ref. 12251).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
