Down Species Information
Size 75mm or 3" SL. Find near, nearer or same sized spp.
Identification A very variable species. See catfish of the month link below.
Occasionally confused with Brochis spp. but can be distinguished fairly easily by the number of rays and shape of dorsal fin - Corydoras have less than ten rays, Brochis have ten or more rays.
Sexing Males are smaller (up to 65mm) and slimmer. Females grow larger and are much wider which can most easily be observed from above.

Down Husbandry Information
Feeding All prepared and suitably sized live foods are taken. User data.
Furniture Substrate should be fine sand, bordered with driftwood and aquatic plants leaving an open area for them to search for food and swim.
Compatibility A perfect citizen.
Suggested Tankmates Keep in a shoal of at least 6 individuals - ideal first catfish for a beginner's community aquarium.
Breeding Easily accomplished with captive raised stock. Some colour varieties are more challenging than others. Given the presence of a suitably egg-laden female and a mature male or two, spawning can be triggered by a large, cool water change. Try changing 30-40% of the aquarium water (at 21°C) and bring the temperature down to 16°C. Do this slowly over an hour or two.The fish should respond by spawning in the classic 'T' formation method.
Here, using one of his pectoral fins, the male clamps the female to his side by her barbels and fertilizes a small batch of eggs held within the protective basket formed by her pelvic fins. The adhesive eggs are then placed on plants or aquarium walls and the process repeated. The eggs take 3-4 days to hatch. It is safe to leave well fed parents with the eggs, but some breeders prefer to remove the eggs, or indeed parents, to avoid any temptation of an easy snack.
For the first few days of their life, pre-soaked powdered flake food should be fed to the fry. After the first 3 or 4 days, newly hatched brineshrimp can also be sparingly used to bring on the fishes growth. As the fish grow more and more foods can be offered in line with the size of the developing juveniles. Adult colouration is reached in around nine weeks.
