Serpae tetra looks messed up HELP

[Andreas Georges]

My Serpae Teta looks like it’s beat up, it’s fins are ripped and it’s face looks deformed, I’ve had this fish for one and a half years and have never had this problem. All of my other fish in the tank are healthy, it’s a 55 gallon.

What tank mates are with him in there? Do you have any decor that he could have got stuck in?
