Ok so I have a cory who was in a group of two...pretty sure they were just green cories. They looked plain. His buddy died the other day, and now he's hiding, colorless, and he freaks out and spazzes all over the tank when I go near it. I have many other cories, and I even added a new group of greens for him to buddy up with, but he's not buddying. I'm worried he's going to die from stress, and wondering if it would be helpful to put him in a hospital tank by himself, or would that just be more stressful?
 
Tank size? Water permeters please.
 
Sorry. It's a 40 breeder. Ammonia measured at .25, no nitrite, nitrates 5. I did a 25%water change, and dosed it with prime. I have 6 pandas, 5 reticulated, 6 greens, and congos. Theres nothing wrong with any of the other fish.
