Etymology: Corydoras: Greek, kory = helmet + greek, doras = skin (Ref. 45335); tukano: Named after the Tukano, an Amerindian group from the upper rio Negro and Japurá/Caquetá basin in Brazil, Colombia and Venezuela..
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Tropical
South America: Rio Tiquié and its tributaries in the upper rio Negro Basin, Brazil.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.1 cm SL male/unsexed; (Ref. 51470)
Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal soft rays: 7. Distinguished from all its congeners, except Corydoras reynoldsi and C. weitzmani, by its color pattern consisting of three large, dark blotches, the first one "mask" on the head, across the eye, the second one on the trunk at the level of the dorsal fin, and the third one on the trunk at the level of the adipose fin. Differs further from C. reynoldsi mainly by the development of trunk blotches; and from C. weitzmani by the presence of a dusky saddle between the dorsal and adipose fin, the second trunk blotch extending vertically from the adipose-fin base to the anal-fin base, and the presence of four dark, vertical stripes in the caudal fin (Ref. 51470).
Facultative air-breathing (Ref. 126274)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00688 - 0.03823), b=3.02 (2.82 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
