Care:A 80 cm tank with good filtration. Watervalues and environment of minor importance. Very easy to keep.

Temperature:19-26

Feeding:Some food should reach the bottom of the tank

Size:4.5-5.0 cm

pH: 6.0-7.5 Hardness: 2-20

Breeding:Easy to breed. Do a 40-50% waterchange with aged water which should reduce the watertemperature 5 degrees or more, temperatures of 16 degrees are not a problem. . Do this every other day for a period, until they start to breed. For their size, large numbers of eggs are produced(up to 100).

Sexual dimorphism:

Prices:Netherlands 2-3 Euro for normal fish.

Additional:This could be an "old" species. Many of the other corydoras could easily have developed from this fish, like C. panda, C. melanistius, C. davidsandi, C. metae, C.sychri. All of these and many others require only small modifications of this fish, like changing the black pigment a bit. This doesn't sound so strange anymore when one takes into consideration that two different species develop the same colorpattern in the same river. If you compare this fish with C.metae the step wouldn't be too big.
