|Cat-eLog Data Sheet|
|Scientific Name||Corydoras atropersonatus Weitzman & Nijssen, 1970|
|Common Name(s)||Fairy Catfish|
|Type Locality||Río Conambo at mouth of R. Shione, Río Tigre system, Ecuador, about 2°00'S, 76°30'W.|
|Pronunciation||Kory DOOR ass - at row person ATT uss|
|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. Latin ater = black, personatus = masked.|
|Size||50mm (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.
Corydoras atropersonatus is similar in colour pattern to C. sychri. C. sychri is a larger fish, has a pointed snout and has more, finer spots.
|Sexing||Female is fuller (when viewed from above) and larger.|
|Distribution||South America: Ecuador: East Pastaza state, Rio Tigre system & Peru: Loreto State, Rio Nanay

|pH||5.6 - 7.0|
|Temperature||21.0-24.0°C or 69.8-75.2°F (Show others within this range)|
|Feeding||Sinking catfish pellets and bloodworm.|
|Furniture||Needs a rounded substrate or sand. This species is prone to barbel loss at the hands of inept water management / inappropriate substrate.|
|Compatibility||Peaceful, keep in groups of 6 or more.|
|Suggested Tankmates||Most small community fish. Tetras are ideal.|
|Breeding||Breeding tank size = 450 x 200 x 150mm. Water Temp. =76 deg F. Ph =7.2 GH = 6 spawning. Followed the typical ''T'' formation two days after a water change which reduced the temp. by 6deg F. A total of 80 1,5mm diameter eggs were laid between three and five at a time. The eggs were all deposited on the tank sides. The adults were removed when they were observed eating more eggs than they were laying. Once the adults were removed a 50% dose of anti fungal solution was added to prevent infertile eggs from contaminating the fertile ones. 60% of the eggs proved fertile and the fry started to emerge on the fourth day after the eggs were laid, and in a further two days the fry were free swimming and were given their first feeding which consisted of pre-soaked powdered flake food followed by freshly hatched brine shrimp the following day. The fry grew at the following rates. At 7 days = 4mm. At 14 days = 6,3mm. At 1 month = 8,5mm. At 2 months = 13mm Adult colouration was reached in 10 weeks, and in 3months they were 21mm long. 49 fry reached adulthood.|
