   The Julii Cory is probably the most popular and often sold Cory. It is active and very pretty! It has bold central horizontal stripes, a spotted body, and six spotted bands on it's tail!

   The Jullii Cory or Leopard Catfish does not grow very large, growing up to only 2.0 inches (5 cm). which makes it very suitable for a small aquarium.

   Like all the Corys, they are quite hardy, very peaceful, and they help keep the bottom of the aquarium clean by eating up leftover foods!

For more Information on keeping this fish see:
Guide to a Happy, Healthy Freshwater Aquarium

Distribution:

Social Behaviors:
   The Julli Cory or Leopard Catfish generally a good community fish. They swim in schools and can be kept with almost every other community type fish.

Sexual Differences:
   Sexing is difficult, and breeding is best accomplished by natural pairing.

   These fish will swim on the bottom of the aquarium.

Acceptable Water Conditions:
   Hardness: 2-25° dGH
   Ph: 6.0 to 8.0
   Temperature: 22-26° C (72-79° F)

Breeding/Reproduction:
   The Corys have a very interesting breeding routine. After bumping the male on the vent, the female will receive the males sperm into her mouth. She then discharges a few eggs which she catches and clasps with her ventral fins. Then the female will swim around and deposit a bit of sperm and just a few eggs at a time in select spots, such as a strong plant, the heater tube or ever the aquarium glass. When she has runs out of sperm, she will go back to the male and repeat the process until the spawn is complete. See the section on Corys in Breeding Freshwater Fish.

Availability:
   The Julli Cory or Leopard Catfish is readily available.

Julli Corys are great! I used to have one but since they get along with my 4 Zebra Danios and 4 Neon Tetras, I'm going to get another one in a couple of days. Brandon T 2009-05-25
I have a school / shoal of 10 jullis in my 5" tank, they have been in for 2 months now and are exceptional tank mates for the rest of the fish , even inducing some of their more stoic tankmates to imitate their erratic behavior at times. I would recommend the species as an excellent addition to any starter tank, but please let the tank become established first as they seem to thrive on the detritus and residue. Another note, as was posted earlier, ensure the substrate does not contain sharp / angular gravel as this not only could damage their undersides, it will also, eventually wear away their barbels.

I got 2 more Julii cory cats. The pet shop in my town finally got them in. I'm glad the owner was able to get them. She saved me 2 of them, so now I have 4 Julii's. They school around together. Sometimes when one swims, then they all follow. They're always doing something. I love to watch them swim. I love my Jilii's. kathy 2008-10-09

I have 1 Julii. I love it. I also have 2 spotted corys. I wish I had more Juliis, I also love any corys as well. kathy 2007-11-08
Some of the coolest comments:
Just as a word to the wise, a lot of corydoras sold as juliis are actually trilineatus. You have to look at the two, very closely to figure out which is which. The trilineatus has a reticulated head pattern (little squiggly lines) whereas the true julii has a head pattern made up of little individual dots. ps: the photo for this section appears more like trilineatus than julii. A clearer photo would help people identify the correct corydoras species. Editor's Note: Anyone with a clearer picture, please enter it into the gallery and we can replace this one.

It is always necessary to have bottom feeders for community tanks, as they work to help you rid your tank of any leftovers. They are highly recommended due to their beautiful appearance, their gentle behaviour, and adorable looks. Avoid adding to tanks with quiet & still fishes, as their active nature will probably be offensive. Henry Chua 2003-09-06
