I see that in the pet store every day The bettas are kept in tiny little clear boxes at the top of a huge tank so they can get used to the other fish that are all around them..

I'm not sure, but I always here people say that bettas are strictly solitary. If they are, then why are they training them like this so they can be housed together later on???

They also have little plastic cups filled with them at petcetera. You know those clear flimsy plastic cups that you take camping??? Yeah, those. They are on a low shelf, and any kid could just run by and every single cup would fall! "Whoops, there goes all 100 of our bettas"
