Julii Corydoras Fish (Corydoras Julii)
Julii corys, also known as Leopard Corydoras, are cute bottom dwellers that will clean your tank with the sensitive barbels they use to root around for food at night. But any fish attempting to swallow this diminutive catfish will be in for a painful surprise of spikes and armor. This fish has the ability to rotate the eye, which gives it the appearance of winking. Fishkeepers often find this fish quite entertaining and endearing.
Indigenous to the lower Amazon region, primarily the Parnaíba River of Brazil, Corydoras julii is found in flooded forest regions as well as in creeks and small tributaries. It is often confused with Corydoras trilineatus, a species that is found in the upper Amazon.

I’ve had my Julii Corydoras for three months now and they’re very active at night. The fish are clean and peaceful, and their winking behavior is adorable. They don’t bother other fish and stay near the bottom where they forage for food.

The fish are easy to care for and fit well in a community tank. I noticed they’re very curious and often explore the substrate. They don’t eat much but seem to be happy with regular feeding.
