My fish is acting weird...

Here is another video of her gramma.
 
I've noticed that all of the videos seem to have the lights off. How does it swim when the lights are on? Do you have any light that is reflecting into the tank from below. Maybe its confused where the sun is and is swimming upside down because of it.. (reaching for straws here). I even went to WWM and looked but really didn't find anything like this.
 
Yeah the light was on when it started doing it and then they were off and she still did it. The thing is that it was under the filter and was shaded. She is now back to normal and seems fine. We just think she is autistic.
