Thats a bad quality video of it lol and I dont really see the mollies bothering him. They did the first day but haven't really cared since. And I JUST found about about water hardness. I thought everything I needed to check came in my API but I pulled this off my towns lists
Yeah, the molly's certainly don't seem to be much of a bother for the dude. Keep in mind I do not keep bettas, but I would attribute the odd behavior to him adjusting to the tank. Watch for aggression, but especially after seeing your aquarium, I think he was just taking a snooze. Maybe someone else can comment more about the stocking or erratic swimming.
