Maturity: L_m ? range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 11482)

Lives in empty barnacle shells. Often perches in the opening with only the head protruding. Seldom seen in the open. Darts out to nab bits of floating food (Ref. 5227). Oviparous (Ref. 56066). Eggs are attached to the walls of the parent's shelter and are brooded by the male parent (Ref. 56066).

Oviparous (Ref. 56066). Males guard the eggs until they hatch (Ref. 56066).

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 25.6, mean 23.8 °C (based on 20 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00219 - 0.01260), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 172 [84, 323] mg/100g; Iron = 0.903 [0.516, 1.590] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.105 [0.054, 0.200] g/100g; Selenium = 19.9 [8.7, 46.4] μg/100g; VitaminA = 337 [106, 1,109] μg/100g; Zinc = 2.18 [1.38, 3.25] mg/100g (wet weight);
