ltshinthebetta, that sounds like a good idea to me x3
I seem to like the small 2.5G-ish tanks for bettas because I can bring them right to the sink to wash or carry with all the water in to do a change.
One day, I'll start getting bigger tanks with filtration and everything though xD
To everyone else, I agree! Like most people, I was brainwashed by pet store people that bettas are one of the most unlively, boring fish ever. All they do is sit at the bottom and never move. I ended up purchasing Caesar as an impulse buy and now I don't regret it at all! Now I know why some bettas never move (poor care, not the fish itself!), and well, I'll tell you....my betta is always swimming about and doing funny things =D
