My betta swims in circles and squares!!!

[kirby13580]

Why does my betta swim in shapes? After i taught him how to swim in circles ( 4 weeks ago), he does it non-stop! the only thing that can lure him out of it is food. Can anyone explain? If your betta had done other weird things you can post it here also!

He's probably glass surfing. My betta Cameron does it. I upgraded his tank and that seems to have calmed it down a bit. Also you could put some plants in the area where he does it and that seems to do the job too.
I know for a fact Cameron does it because he gets bored too easily. I put colorful objects on the outside of the tank or over his head on the glass top of his tank. Things like that seem to keep bettas occupied for hours!

What size is his tank? As MB said a fish that is bored will engage in repetitive behaviors like that. A bigger tank with decorations and plants will distract him and his behavior will return to normal.
