Well, Relic, there is merrit to what you say. I also keep fish, some, jarred right now. Partly because I am going to be moving them all into large, long, separated tanks with rooms for everyone soon. However, I change my water every other day for everyone, and while that sounds like a great idea at first, it is SO easy to just think "they can wait one more day"... and eventually, you get a fish forgotten, with no fresh water, no friends, and then they get sick and die. the point I am trying to make is this: whatever "tank" you use, please consider whether a larger one will allow you to care for your fish just a little better, especially if you find yourself "forgetting" them. Mine are all grouped with buddies, and since I am such a behaviorist, I spend a lot of time with them, just watching their interaction. But if a person isn't obsessed like me, please choose a bigger tank so a tendency toward natural forgetfulness does not hurt your pet. Whatever the case may be, bettas can NOT live in a vase eating a plant for nutrients. That is ridiculous and ghastly. You go live in your backyard and eat the grass you pee on. Then get back to me!
