Biology     Glossary (e.g. epibenthic)

Feeds on worms, small crustaceans and plants. In captivity, spawning takes place among plants and eggs usually hatch in 20 to 24 hours (Ref. 7020). Maximum length reported to reach 4.5 cm TL (Ref. 7020). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00888 (-0.21703 - 0.23479), b=3.24 (3.12 - 3.36), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.31 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
