Netflix really does have a lot....
I am a die hard Dragon Ball and Dragon Ball Z fan. :) The graphics are just so insane, especially the Japanese versions, so I get way into it.
What country do you live in? We have people from all over the world! It is mainly US, though. And we're all very much into bettas, maybe *obsessed* even? You'll understand soon enough, LOL
As for filters, they are great, but basically all of them need baffling. Decorations are a must, they really enjoy hiding places and floating things to sleep on. A lot of decor can be found very cheap, too.
