Pink kissing gorumis, with others?

[Ethos]

I have a brown cory, and I use to have a albino cory
But with those 2 i could always find them apart...

The 'brown' must be a bronze (c. aenus). Albino cories are usualy albino bronzes as well. So the two cories were actualy the same species. realy though, cories will school with cories that display the same color pattern. I always reccomend having at least 2 of any given species/color morph in a tank but a minnimum of 4 cories in total (eg: 2 peppered with 2 bronze). You'll find that if you do keep several of the same species and variety they will school and are one of the most social fish. If possible, I would add another bronze cory to your tank (if there's room) or move the cory into something larger and add 3 more at least.

My tank is already alittle over crowded at the moment. Will it add more stress if I add 2 more corys?

Do you have a different tank to move the cory you have into and then add 3 more? If not, and you know your tank's a little over-stocked, you should realy be looking to upgrade anyway. Then, once you get a large enough tank, you can add at least 1 more cory. In your current tank, I wouldn't add another and risk over-crowding even more.
