Scientific NameCorydoras weitzmani  Nijssen, 1971
Common NamesTwosaddle Corydoras
Weitzmans Pansermalle (Denmark)
Type LocalityRío Vilcanota system at Cuzco, Cuzco, Peru, 13°32'S, 71°57'W.
PronunciationKory DOOR ass
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. Named to honour Dr. Stanley Weitzman.

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.

Fairly unique in that it has a light brown body with three dark markings, one over the eye, one under/into the dorsal and one at the end of the caudal peduncle. The exact shape of the spots varies somewhat from one fish to another.
SexingFemales fuller bodied and slightly larger than males.

DistributionThe type locality information recorded for this species is inaccurate. It was collected in the sixties by Paolini in his many expeditions in the area and vaguely recorded as from "near the Cord. Vilanota". The 1971 description from his preserved material made the final leap to the incorrect locale. It was not until Belinda and Lance Peck found the species again in 2003 that imports to the aquarium trade started. Those imports come from the Rio Araza in the Madre del Dios river system in Southern Peru.

FeedingWill accept a wide range of commercial foods including tablets, granules and flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm, Daphnia and tubifex are readily accepted.
FurnitureShade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required. Ideally substrate should be sand, but rounded gravel is an imperfect alternative. Avoid keeping over rough edged (chipped) gravel, this will increase this risk of damage the fishes barbels when it tries to dig.
CompatibilityComaptible with all but the tiniest of fry, and as long as they are not considered "food" in themselves.
Suggested TankmatesIdeal tankmates are small to medium tetras. Possibly also dwarf cichlids such as Apistogramma or Mikrogeophagus.
BreedingHas been bred in the aquarium and appears to be both reasonably easy and predictable in its spawning behaviour.
