Indian Ocean: from the Maldives, Chagos Archipelago, Seychelles, Madagascar, Comoro Islands, and along the East African coast between Shimoni, Kenya and Bazaruto, Mozambique.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.9 cm SL male/unsexed; (Ref. 122787)
Adults occur in clear lagoon and seaward reefs, usually in loose aggregations near caves and ledges. Abundant over branching corals and leeward coasts (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00792 - 0.03811), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
