Corydoras acrensis • Callichthyidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Corydoras acrensis** Nijssen, 1972
Common Name(s)	Acre Corydoras
Type Locality	Furo do Lago São Francisco, 7°40'S, 72°39'W, trib. at left bank of Rio Juruá, Est. Acre, Brazil.
Pronunciation	Kory DOOR ass - ack REN siss
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 for the Brazilian state of Acre where the specimen was originally collected.
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.
Sexing	Females 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.
Habitat Information
Distribution	South America: Juruá River basin. Amazon, Juruá (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	6.0 - 8.0
Temperature	21.0-24.0°C or 69.8-75.2°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.
Suggested Tankmates	Keep in a shoal of at least 6 individuals.
Breeding	Unreported.
