Adults live in empty tube-worm snail shells, often extending the head from the opening. They feed by joining loose groups of look-alike rainbow wrasse and darting out to nip at nearby fish, taking mucus and perhaps small bits of flesh (Ref. 5227). The skin of larger fishes is the mainstay of the diet, although they are also known to eat eggs (Ref. 28023). Oviparous (Ref. 205). Eggs are attached to the walls of the parent's shelter and are brooded by the male parent (Ref. 56053). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, distinct pairing (Ref. 205). Males guard the eggs until they hatch (Ref. 56053).

Estimates based on models
Preferred temperature (Ref.
123201): 22.5 - 29.1, mean 27.1 °C (based on 214 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00253 - 0.01308), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 4.4 ±0.78 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
