"This is definitely better than most betta bowls. In my opinion, it's easier to catch the betta, and easier to clean. I think it's a more suitable size as well. It mounts very easily onto the wall, and is easy to take off and place back on when cleaning.
The best thing about it is that it's different! Anyone that comes in and sees it on our wall asks, "Is that really a fish bowl with a real fish in it?!" It's definitely unique!"
