so it's actually a wide area of pink from pectorals to tail? at first reading the description i was thinking a line.
it could be irritation or it could be infection. yeah as mentioned remove any sharp object. add salt and do water change and see if it gets any better.
is it losing any slime coat on the belly? do you see red streaks lining the scales? Do you know how long it's been like this and if it has gotten redder during that time?
