Hi, TimtheBadAss...your TSN's nose if it was broken is not likely to heal back to what it was. Kinda' like a fighter...once the nose is broken unless you have surgery (which doesn't usually completely fix the look) you can always tell the nose has been broken. Also as a result, he likely has a bit of an underbite...that is not likely to change either, but it will not stop him from being himself. The nose will be tender for a bit, but eventually only you will remember that he broke it because you are looking at it all the time wishing your fish hadn't been hurt.
Mine spooked when an air tube came off and we woke up to a very badly cut bent nose. The cut healed very quickly because he is really healthy, but the nose (three months later or so) is still bent.
