Cat-eLog Data Sheet
Scientific Name	**Corydoras weitzmani** Nijssen, 1971
Common Name(s)	None
Type Locality	Río Vilcanota system at Cuzco, Cuzco, Peru, 13°32'S, 71°57'W.
Type Locality Map
Pronunciation	Kory DOOR ass
Etymology	Cory = 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.
Species Information
Size	55mm (2.2") SL. Find near, nearer or same sized spp.
Identification	Corydoras 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.
Sexing	Females fuller bodied and slightly larger than males.
Habitat Information
Distribution	The type locality information recorded for this species is inaccurate. Imports to the aquarium trade have come from the Rio Madre del Dios reiver system in Southern Peru. Amazon, Middle Amazon (Solimoes) , Madeira, Madre de Dios (hover or click on these areas to show maps or find other species found there)
pH	6.0 - 8.0
Temperature	22.0-26.0°C or 71.6-78.8°F (Show others within this range)
Other Parameters	dh 2-25.
Husbandry Information
Feeding	Will 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.
Furniture	Shade 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. Do not keep over regular, not rounded gravel, this will damaged the fishes barbels when it tries to dig.
Compatibility	Comaptible with all but the tiniest of fry, and as long as they are not considered "food" in themselves.
Suggested Tankmates	Ideal tankmates are small to medium tetras. Possibly also dwarf cichlids such as Apistogramma or Mikrogeophagus.
Breeding	Has been bred in the aquarium and appears to be both reasonably easy and predictable in its spawning behaviour.
