Julli Corys are an entertaining fish for aquarium keeping hobbyist. They have the unusual ability to rotate their eye, making it appear as if it is winking. As a bottom-dweller, they will keep the floor of your tank clean. By using their barbels to root around for food at night.
Julli Cory will consume most food that finds its way to the bottom of your tank. This does not mean they are getting enough to eat. Try sinking tablets or pellets as their primary diet. And feed them live food like brine shrimp or bloodworms via tongs to supplement. They are also nocturnal, so complete feeding activities right before tank lights turn off. Keep Julli Corys in a school of at least five in a tank that can accommodate them comfortably. They will get along with other small catfish and small peaceful fish. Try Tetras or Dwarf Cichlids.
These are an undemanding species of catfish and can tolerate a range of water parameters. As bottom-dwellers, having a rigid substrate could cause injuries. The substrate needs to be soft because they will scavenge. Try smooth gravel or sand. Driftwood is a good addition as it can serve as a hiding spot. Jullis do not enjoy bright lights so you could try floating plants.

The physical appearance of Julli Cory is very similar, to see a clear difference, look at them from above. Females will appear rounders and broader in their body than their male counterpart. The female will also look plump with eggs. Breeding this species is consider doable for a home breeding enthusiast.
