I just moved 5 peppered cory catfish from a 5 week quarantine in a 10 gallon to my 90 gallon community tank 3 days ago. Yesterday I noticed one of the corys, the smallest I believe, was stuck upside down between the leaves of a small sword plant. I moved it back to the 10 gallon and it is still alive but seems very tired and is hiding in the corner between a sponger filter and some wood. I put a piece of sinking wafer in and the cory did eat it but it still seems to move a little awkward and mostly just sits in the same place. I do not see any external physical injuries.
What is wrong and what should I do to help it recover?
