Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.8 cm SL male/unsexed; (Ref. 11333); 9.7 cm SL (female)
A single, ovoid terminal bulb 1-1.2% SL. Barbel length short to intermediate 32-60% SL. Short terminal filaments 9 or more of various sizes; shortest filaments often bulblet-tipped; longer ones with bulblets and inclusions of various sizes and shapes; 1 filament thicker and longer than others, not forked, with 1 or more long inclusions filling most of its distal end. Axis of stem lightly or not pigmented. A dark spot usually at the base of the bulb. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 7 (Ref. 11333).

Estimates based on models
Preferred temperature (Ref.
123201): 16.2 - 27.8, mean 26.1 °C (based on 18 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
