Distinguished by the following characteristics: small; brightly colored with reds, browns, blues and yellows arranged in spots, bars, or stripes in varying combinations (Ref. 92840).
Lives in crevices and deep recesses in the rocks. Like other Elacatinus, this species is a cleaner; it picks parasites from other fishes. In areas of the reef where there is a floor of sand that is protected by an overhanging ledge, reef whitetip sharks may be observed lying about like a stack of cord wood. It is in these areas that this goby lives and it can clean the reef whitetips (Ref. 28023).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
