Environment
The Cory is an ideal catfish for the community aquarium, should be kept on a soft sand substrate and maintained in groups of 5 or more due to their shoaling nature. Some heavily planted shaded areas should be provided also. Corydoras have the ability to breathe air intestinally, so leaving a small gap between the surface of the water and the cover slides should be done in order for the fish to come up to the surface and take air in. They may do this numerous times per day.
What’s for lunch?
Sinking catfish pellets, frozen foods such as mosquito larvae and brine shrimp. Although they will also sift through substrate for any food that may end up there such as uneaten flakes etc.
Breeding
Mature pairs can be triggered into spawning by performing a large, slightly cooler water change. The pair will adopt the classic ‘T position’ where the male fertilises the eggs that are held between the female’s pelvic fins. The adhesive eggs will then be deposited onto plants, décor, or the sides of the aquarium etc and the process repeated. The eggs generally take 3-4 days to hatch after which time the tiny fry should be offered finely powdered first foods. A few days later they will be able to take newly hatched brineshrimp.
