Wow! I'm glad I found this thread. I have a compressicep that has a similar condition but with a kind of bent nostril. I thought he got into a fight with my electric yellow cichlid and lost since the cichlid was much bigger than him and always picked on him.
He doesn't show any signs of stress or loss of appetite. Maybe I should try to massage his mouth and see if it helps...
