What size tank? How does your water test for ammonia, nitrite, nitrate, and ph?
If your tank is large enough and water quality is good, I would add a few more of the same type cory.
They like being in groups of 3 or more. I had the skunk cory, they where a very tight group and did not hang with the other types of cory. They stayed in their own group.

Cories rarely cross breed.. So it is better to have 6 of all the same species.

oh its not my tank so im not aloud to add more fish but ill ask cause i had two to begin with then i asked my stepfather to put in one more because they are better with up to 3 together so we did. but its so hard to tell male from female.

Cories are almost impossible to sex. They are shoaling fish and feel more comfortable with bigger numbers. It doesnt matter if you have males or females. You could add more if you want to make them happier. Most people recommend a minimum of 6.

Female corydoras are usually more plump than the males.

well i think i have 2 males and a female but they dont crossbreed that stinks

Just wondering... Why are you interested in breeding every fish you have?

I had a breeding group of 9 cories,and they bred all the time! Once you get into it,you get overwhelmed if you can't sell them fast enough. I had four tanks of cories by the time I said enough is enough. lol Won't be going back down that road anytime soon.
