That's the problem. I could only see new owners impulse buying this because it looks easy, cute, and like it won't take up much room. As I mentioned earlier, I don't see a problem with breeders holding fish in bottles because some breeders breed to sell to permanent homes and the ones who don't sell the fish at least know what they are doing as far as water quality is concerned. Like Phaydra said, a new owner would kill a betta in one of these in a week-month time frame. Since this is being sold as a gimmick to people who want a novelty item that moves instead of a pet, I think it's bad.
Also, while this may sound like I'm getting on my high horse that is standing on a soap box XD, I don't think "keeping a pet alive" is good enough. I wouldn't expect a breeder to have 5 gallon tanks for each of his/her 100+ fish. However, I would expect a pet owner to be able to do a bit more than the bare minimum for 2-3 fish. My set up on campus was a 1 gallon tank, 3i Whisper filter, thermometer (heater came later when I wasn't in a constantly hot dorm room), a castle to hide in, and a small silk plant at a time when I was bappy to see more than $5 in my checking account.
I don't have pictures of it on my work computer, but the person who can afford that gimmick can afford the proper 1 gallon set up I used on campus. I don't think this is a bad idea because of the bottle's size. I think it's a bad idea because I think it's stupid. XD
