Yah, bettas are a very active and happy fish when they are healthy. I love them. I used to have one before I knew much about aquariums but I did do months of research... still issed a lot of things ig lol. Have you tried drawing on the tank with a dry-erase marker? They will chase it around... Its so funny. Just dont do it a ton cause too much fun with that is stressfulI have hornwort in his tank that he loves to rest on, and I just put in a new variegated plant with broad leaves that he is really really enjoying!
I love it when he comes out and plays. He is the most active betta I have ever seen
