|Cat-eLog Data Sheet|
|Scientific Name||Corydoras simulatus Weitzman & Nijssen, 1970|
|Common Name||Olga Cory|
|Type Locality||Río Ocoá near Puerto López, 4°06'N, 72°57'W, R. Meta system, Meta, Colombia.|
|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. This specific epithet literally means imitation(simulatus=imitation, copy), in reference to its similarity to Corydoras metae.|
|Size||70mm or 2.8" 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.|
A long snouted species, having a tan coloured body with a black band along the ridge of the back from the base of the dorsal to and across the caudal peduncle. There is also a black vertical eye mask.
|Sexing||Sexing Corydoradinae catfishes|
|General Remarks||This species is one of only four which posses a third pair of rictal barbels, these are only small and can only be seen when the larger outer barbels are in a forward position.|
|Distribution||South America: Upper Meta River in Colombia.|

|pH||6.2 - 6.4|
|Temperature||20.0-25.0°C or 68-77°F (Show species within this range)|
|Feeding||Will accept most commercial flake, tablet and granular foods. Small crustaceans, worms and insect larvae form the basis of their natural diet and where ever possible should be offered as and when available.|
|Furniture||Fine smooth grained sand substrate.|
|Compatibility||Peaceful, but may become aggressive to own kind during mating season.|
|Suggested Tankmates||Any non-boisterous fish.|
|Breeding||C. simulatus were spawned in a fish house in the U.K. where the heating was turned off at the end of April and back on again towards the end of September. This resulted in a 24 hour temperature variation of between 8 and 10 °F. Weekly water changes were made as normal, no extra cooling was needed to trigger the spawning. When the fish were ready they followed the normal Cory 'T' formation mating clinches and spawned. A single female produced 150 1.5mm diameter light amber eggs. These were placed on the tank sides and in the spawning mops. Spawning mops should be provided as the fish appeared to prefer these to Java Moss.|

Wild caught. Update: One died the next day sadly, so went back and bought the remaining two for a quartet. One seems more aggressive than the other three and chases the others quite a bit.
Update: Sadly down to just two individuals. They seemed to have a hard time adjusting to my water (hard and high ph). I have a bag of oak leaves in the tank and have been mixing purified and de-chlorinated city water with my well water. The two corys left seem to be doing well though, eating and busying themselves about the tank.", (17) sushi1980, (18) Narwhal72, (19) scandicman (k: 4), (20) Mol_PMB, who also notes: "These are the variety with the dark blotch.", (21) KillieOrCory, (22) KeXx (k: 7), (23) Junglejason.|
