IUCN Red List Category	Not Evaluated
pH	6.4 - 7.0
Temperature	23.0-26.0°C or 73.4-78.8°F (Show species within this range)
Husbandry Information
Feeding	The usual fare for adult Corys, a good quality flake food, tablet food, frozen bloodworm and whiteworm used sparingly. I fed the fry with infusoria to start off the first few days, then on to Brine shrimp nauplii, Microworm, fry and crushed flake. User data.
Furniture	Planted tank with a few hideaways; that way they will feel secure in their environment, and you will see them out in the open more often.
Compatibility	Peaceful
Suggested Tankmates	Certainly will enhance your community tank as long as it is at least 24'' long with 36'' being a better option. The usual community fish will suffice, but I am suspicious of a few of the Barb family as they do tend to nip the dorsals of Corydoras, so pick carefully.
Breeding	Using a 18'' x 12'' x 12'' tank with sand, Java moss, Java fern and a sponge filter. They spawned at a water temperature of 78F, a pH of 6 and GH 1. The eggs (shown above) are quite large, measuring 2mm and a creamy white colour. The first spawning yielded only 8 eggs but the second, 7 weeks later, amounted to 25 eggs. They laid eggs on and off for the next year then suddenly stopped for a year. The fry look like any other Cory fry having spots over the top half of the body and gradually begin to resemble the parents after 6 weeks, with pale orange fins, and a dark head which has quite a steep incline, making it look quite chunky.
Breeding Reports	There is no breeding report.
