Mix of Corys?

Hello,

In my relatively new tank I have, so far, 6 zebra danios and 2 three-striped corys. I would like to add 2 more corys. Do I have to add the same corys as I currently have, or can I get 2 more of a different type? I read here they like to group, but will that make a difference if they are not exactly the same line of cory?

Thanks!

Aw, crud! I did a search of these forums before posting and I still missed it!

Thanks for pointing me in the right direction!
