Storlek / Vikt / Ålder
Könsmognad: Lm ?  range ? - ? cm
Max length : 13.0 cm TL hane/ej könsbestämd; (Ref. 7251)
Taggstrålar i ryggfenan (totalt) : 11; Mjukstrålar i ryggfenan (totalt) : 15; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 15. Black spot in the dorsal fin is in the lower half of the fin and is usually located between the 6th and 9th spines; there is some brown pigment at the corner of the mouth but no black and white bands inside the maxilla (Ref. 13442).
Body shape (shape guide): elongated.
Adults inhabit an elaborate burrow, often fairly deep (12 inches), and with a terminal chamber; the vertical shaft lined with coral and shell fragments. Males are oral brooders (Ref. 5521). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884).
