Scientific NameCorydoras leucomelas  Eigenmann & Allen, 1942
Common NamesPanzerwels (Germany)
Sortfinnet Pansermalle (Denmark)
Type LocalityYarina cocha, cutoff lake at right bank of Río Pacaya, near Sarayacu, about 5°15'S, 74°15'W, Upper Amazon, Peru.
PronunciationKory DOOR ass - look oh MELL uss
EtymologyCory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. The specific epithet, leucomelas means ''with white and black''.

Size 55mm or 2.2" SL. Find near, nearer or same sized spp.
IdentificationCorydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

A very easy fish to misidentify as it is often captured alongside the similar species C. agassizii and C. ambiacus and C. gomezi. C. gomezi has a distinct black spot on the dorsal, C. ambiacus grows larger and lacks the distinct ''mask'' marking through the eye and C. agassizii also lacks the ''mask'' and has much less black on the dorsal. Expect to find these four spp. mixed in many Amazonian Corydoras shipments.
SexingFemales grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
General RemarksC. leucomelas is known amongst collectors in the Amazon as ''Maldito'' (the little damned Cory) because it is so common that it brings a very low price. As of 2003, collectors in Leticia, Colombia received U.S $7.00 for every 1,000 C. leucomelas they sold to Bogota exporters. It is still collected, however, as many thousand can be captured in a few hours since it is always found in very large schools.

DistributionOne of, if not the, most common of the upper Amazonian Corydoras sp. This species is common throughout the main river channel and several smaller tributaries in the Ecuadorian, Peruvian, and Colombian Amazon. It can also be found as far downriver as Tabatinga, Brazil. Most commercial collection takes place in Peru and at Leticia, Colombia.

Jump to next section Husbandry Information
FeedingOmnivore. Happily takes dry, frozen, and live foods.
FurnitureIn nature, found over mud substrates in blackwaters. In the aquarium they prefer a sand substrate and enjoy hiding among plants, rocks, and driftwood.
CompatibilityCompatible with tankmates of any size. This species is always found in large schools and a minimum of four individuals is recommended. In the Rio Yavari, Peru they were captured alongside Rineloricaria, Loricaria, and spotted raphaels.
Suggested TankmatesAll Corydoras should be kept in groups of at least 6 of the same species. Otherwise compatible with most other types of fish that are reasonably peaceful, as long as they don't see a Corydoras as a snack.
