Etymology: Sicydium: Greek, sika, sikya = cucumber ; diminutive (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; amphidromous (Ref. 46888). Tropical; 22°C - 27°C (Ref. 13614)
Western Central Atlantic: Caribbean coast of Venezuela, Dominica, Jamaica, Martinique, Puerto Rico, Trinidad & Tobago (Ref. 50190) and Panama (Ref. 51464).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm SL male/unsexed; (Ref. 50190)
Morphology | Morphometrics
Found abundant in rivers of coastal volcanic topography (Ref. 12113). Adults spawn in rivers with coarse substrate, building nests under stones (Ref. 33036).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Excavates nests below the gravel bottom. Male provides most of the parental care. Newly hatched larve emerge from nests upon hatching and enter the river plankton. They migrate to the sea where they stay for 50-150 days before re-entering the rivers as postlarvae.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming Tmax is > 11 (Bell, pers. comm.).).
Vulnerability (Ref. 59153
): Low vulnerability (18 of 100) .
