Etymology: Corydoras: Greek, kory = helmet + greek, doras = skin (Ref. 45335). More on author: Nijssen.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.0 - 8.0; dH range: 2 - 25. Tropical; 22°C - 26°C (Ref. 13371)
South America: Coastal rivers of Suriname and French Guiana.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.2 cm SL male/unsexed; (Ref. 35381)
Stays in schools of several dozens of individuals (Ref. 35381). Occurs in creeks with sandy bottoms with slow or strong current (Ref. 27188). Swims mostly in backwaters and hides itself under logs or rocks. Its 'locking' mechanism built with its bony plaques, which permit it to keep three spines erected, is a good passive defense mechanism. Lifespan can last for 7 years. (Ref. 35381).

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), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
