could it just be stress or is he injured? he's a greyish color while the others more pinkey, along with the little red dots on his side. he swims okay but he's breathing rapidly. i'll try to get a picture, he was just in the back of the tank so it was impossible before. i figured i may get more responses here than in the emergency section since you guys are cory people .
I'm guessing that if it died about an hour and a half after you posted there wasn't much that could have been done anyway, so sorry to hear that.
But an hour and a half isn't a lot of time to allow for a response when half the hemisphere (and half of the posters) are in bed anyway.
