Do you keep it filled right to the top? Do you find your betta has a hard time finding where to come up for air? Or has he gotten the hang of it. I always like the "cube of water" idea that is this tank but wondered about how bettas would take to it.
I didn't fill it all the way up at first, but I inadvertently trained him to find the open area. I started adding more water and he was able to tell where the air space started and he always goes to the hole anyway when I feed him. Now, he knows if there's no airspace at the top to go to the center hole.
He's a little odd because he likes the current from the filter. If its on high output, he gets in it and blasts himself across the tank. If its on low, its not enough to push him, but now I notice he's started getting in the current and flaring like a sail. He gets the same effect and gets swooshed across the tank. He's a weird little dude.
