The Julii Corydora (Corydoras julii) is a species of small, bottom-feeding catfish. They are characterized by their distinct black and white patterns.
The Julii Corydora is an undemanding fish to keep, and suitable for the beginner fishkeeper. They require a water temperature between 73-79 degrees Fahrenheit and tolerate a pH between 6.0-8.0. Because these fish are sensitive to fluctuations in their water parameters, such as ammonia and nitrite, it is best to introduce these fish to an established/cycled aquarium. These fish do best on a soft substrate, such as sand.
Corydora are shoaling fish, and should be kept in groups of at least 3. A group of 3+ requires at least 10-gallons of water, as these fish grow to be 2" in length.
While these bottom-feeders will eat any foods that fall to the bottom of the aquarium, their diet should be supplemented with sinking foods such as shrimp pellets or algae wafers. It is not uncommon for corydora catfish to starve to death if not fed in addition to their other tankmates.
The Julii Corydora is an exceptionally friendly and curious species. They may be kept with other bottom-feeder species, and do well with most small, docile, community fish species. Do not keep with any significantly larger fish, as the corydora catfish may become prey.
