Yep, I agree. I can't tell if the cory in the corner is the same but it looks like it. How many do you have? 6 is kind of my minimum of schooling/shoaling fish if your tank is big enough.
Purchased 3 more cories this weekend and they've settled in well. They were labeled as green cories, but they're a perfect match. Well...2 of 3 were a match, the other they bagged up is clearly different. I'll see if I can get a picture.
