I'm sure the community is going to be super great!
Yep, Betta's like a lot of cover, it's not so much the size of the tank that bothers them, it's the open spaces. If you think about it, they come from Rice paddies in Thailand and it's literally all plants! So very little open space for them so they inherently are afraid of big open spaces, so even if the small tank is bare, it can still freak them out, you see? That's why I like planted tank, gives a great nature feel, helps maintain great water quality and gives my little boys and girls something to explore all day long and they do! It's really great to watch them when they are so content and not afraid
