How can I make my julli corys less skittish?

I have 2 julli corys and 3 albino corys along with my betta. They all get along great! But the thing is, my jullis are always hidding. They school often with the albinos, so I think that having 5 is a good number? Just curious, because any movement I make even 20 feet across the room seems to make them hide or move frantically. Anyone have any suggestions about how to make them less afraid? Thanks!
 
2 things as suggestions, but this sounds like normal behavior to a large degree (as long as they are not stressed or being hurassed by other tankmates causing this):

- Provide greater cover for them (From both you and the other tankmates)

- Associate ur "presence" with a treat for a while (everytime you walk by drop a single shrimp pellet in for them, just don;t walk by every hour ;) ). <-trust me it wont take long if their 'skittish' behavior is a non-stressed reaction.

Is the betta leaving them alone? They usually do okay togther, but what size tank? The other thing is it check your water to rule out any stress from that as well.

Also, observe them from afar, or take a seat next to the tank and keep still - See if the behavior is caused by anything oir if it is just innocent playing and interacting with each other. This will tell you a lot.

Good Luck, and keep us posted! :)
 
Number 1 = they need to be in groups of at least five, each species, they will not shoal together unless they look alike.

Agreed. I would either switch out one of your groups of increase the size of one to 5+ or increase both species if you have the room in your tank.
 
Like LittlePuff said, usually different species of corys wont shoal together, I'd try to add at least 1 more juli if not 3 more. But another thing you might want to try is just adding some plants if you can. Basically they probably dont like all the light and movement and dont feel secure without more cover.:joe:
 
Hi,

What hiding places do you have? Do you have a lightly planted tank, a medium planted tank, or a heavely planted tank?

I have four species of Cories, and they all love to hang out together under my bogwood. But they tend to like their own species more.

I would suggest to get a couple more Cories. How big is your tank?

BTW, most likely you have Three-Striped Cories (Corydoras trilineatus) and not Juliis. Because Three-Striped are almost mislabled as Juliis. If you can post a pic I can tell you for sure if they are C. julii or C. trilineatus.

My juliis got skittish when I doubled my lighting and removed some floating plants. Now they only come out when the lights are out. The pandas don't have those problems.

actually they shoal no matter, my dad has three or four different types of cory cats and they all shoal together, as if they were the same
 
Hello, Thanks everyone for your help!

First of all, I have 2 jullis, 3 albinos and a male betta. They all get along great-betta does not pick on corys, all 5 corys shoal together. I have a medium 10 gal planted tank, with what I think of as lots of cover.

Here are a few pics of my tank and my so called julli corys. Take a look and tell me if they are or are not jullis as that is how they were sold to me.

I don't think I should get anymore fish as it may be overstocked with more, but I will say that the corys loooove their sand bottom and all the room they have to swim.

Any opinoins would be greatly appreciated.

That is an actual Corydoras julli. I just found some information out on this website about them and found out my cat is actually a Corydoras trilineatus (spotted form) and was marked as the Julli when I bought it since the spotted pattern one is very similar to the Julli.

Good to find out what type of fish I actually have! Here are some pictures of the two different types:
