So Galileo, as I've mentioned, has been one of my most active bettas. He's very 'twitchy,' whizzing around this way and that, and then stopping for a rest, and then going again. I've recently noticed that he's developed a bit of a habit. He darts over to the left side of his tank and swims up and down with his nose against the glass. This is also the side that his Betta hammock is on, so he'll dash over the suction cup and then do what I can only describe as horizontal 'laps' around the left side of the tank. This past time he actually jumped out of the water, and thankfully the tank has a cover, or else I'd have had a heart attack.
This is a video I took of him just a few days ago, before he started going crazy on the left side. You can see his energy, and also the little breaks he takes between bursts.
Anyway, my question is, what could be causing this? Is it just a crowntail quirk? He's my first CT, so I wouldn't really know.
