Etymology: Sicydium: Greek, sika, sikya = cucumber ; diminutive (Ref. 45335).
Environment / Climate / Range
Freshwater; demersal; amphidromous (Ref. 92840). Tropical, preferred ?
Africa: Côte d’Ivoire to the Republic of the Congo (Ref. 57403).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.1 cm TL male/unsexed; (Ref. 57403)
soft rays: 9 - 10. Diagnosis: posterior tip of upper jaw extends to level of anterior 1/3 or 1/2 of eye; each side of upper jaw with 22-36 slender, tricuspid teeth, narrowly separated from each other by median tubercle; upper lip crenate, with an inner longitudinal furrow and a median tubercle just posterior to the median notch; 2 pores in preopercular canal; 2-3 suborbital pigment bands (Ref. 57403).
Amphidromous freshwater species (Ref. 92840). Inhabits fast flowing parts of rivers that have rocky substrates and usually associated with rainforest zones (Ref. 10702, 57403). Maximum observed SL was 6.63cm (Ref. 10702). Seems evasive and difficult to catch (Ref. 57403).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
