This is a special one. I have better quality footage

of him turning around and around in his tank,

but this is very special and he did it only with very low light.

Puffy was doing perfect circles and swimming FAST!

I counted over 100 laps and stopped counting, but he

was doing this for 6 hours! Perfect circles, top speed,

no mistakes. I calculated that his speed was about

1 mile per hour, so he swam over 6 miles that night.
