So today i came home to my wels catfish spiraling out of control, should i just put it out of its misery? i think he rammed the acrylic really hard and damaged his spine. he swims with his mouth open and upside down. I was heartbroken at the sight since hes my most prized fish right now in my collection. http://www.youtube.com/watch?v=Yo2tQZHLPdc
