Just a note to buggyboutbettas - It sorta seemed like you jumped on Auratus for posting her find, I could be totally wrong, it just read that way to me. Anyways, she was saying this is a much better alternative to the betta vase, which it is. It doesn't have a live plant as an only source of food, it's not extremely tiny, and that site has directions. The tank you posted as a better alternative is about the same size, to tell you the truth. It's not quite a gallon. It does include a filter, which is nice, but not necessary. Bettas do live in stagnant water. I'm not sayin it isn't healthy for them to have a filter, because it is of course, but I don't believe it's necessary.
