Fish Fanatic
One of my Mollies had babies early this last spring, 6 lived. One of them I noticed tends to swim upside down sometimes then straightens out. It'll do "loop de loops" and continue on or even do what I call "the cork screw". He's quite big now like the size of a healthy neon tetra but he still does it. Does anyone know what might be causing this? I've looked closely at all his fins and they all appear normal and his eyes do too. I'm at a loss.
