I currently have a group of 8. Two of them I've had for over 2 years, the others just went into their home tank after 2 weeks in a QT.
Both the old and new kuhlis 'circle'; 1 or 2 will start swimming in a large, fast verticle circle against the glass, over & over...
It's fun to watch and has become a joke with us but we were wondering if this is a common kuhli behavior or not?
Thanks
