Biology     Glossary (e.g. epibenthic)

Inhabits rocky reefs and sandy-weed flats (Ref. 3132). Occurs in aggregations (Ref. 9710). Feeds on algae and zooplankton. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205). Recently discovered in deep water in cold upwelling areas of Bali (Ref. 9710). Unknown to American and European aquarists although can easily be maintained in a tank according to Australian aquarists.

Estimates based on models

Preferred temperature (Ref. 115969): 17 - 26.9, mean 20.5 °C (based on 78 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01165 - 0.04718), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.29 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
