In nature cories are a schooling fish, so many people purport that for them to be happy they need to be in schools of 6 or more (per species). If you adhere to that reasoning, you need to go out and get 25 more cory cats.
I am not sure a fish can be happy or sad, but if you note that they seem stressed...it might be because they would feel more secure with several more members of their species. Also, I've read that in order to see true "schooling" behavior, you need to have 6 or more. I've yet to get my numbers that high, but my cats seem happy enough.
