A while back I had posted about my serpae tetra that swam with his face to the top of the tank, he showed no signs of being sick and has swum like that since I got him, about 3 months or so ago. Today I got out of bed went to say hi to the fishes and gimpy (we affectionately called him that), isn't gimpy any more!
He swims normal now. I am completely blown away. I have no idea what caused him to swim that way in the first place but whatever it was, it isn't a problem anymore. Strange but I am happy for him.
