Taille / Poids / Âge
Maturité: Lm ? range ? - ? cm
Max length : 3.0 cm SL mâle / non sexé; (Ref. 57259); 3.5 cm TL (female)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 6 - 8; Épines anales: 0; Rayons mous anaux: 11 - 15. Diagnosis: Small and slender species with rounded fins and lacking the distinctive colour pattern of the other species of the genus Micropanchax; dorsal fin with 6-8 rays, anal fin with 11-15 rays; scales on mid-lateral series 27-30 (Ref. 57259).
