Ok, so my school librarian had one male betta living in a very small (a tiny bit smaller than the petsmart ones) cup. He had severe pop-eye, finrot, and he was only fed twice a week. I decided to take up one of my study hall sessions to talk to her, and tell her about betta care. I then asked her if I bought the little guy (named tom) a tank if she would use it. she agread so I bought him a nice little 2.5g with all the neccessities, and set him up a home. sadly he got help a little too late and passed away. a few months later the librarien called me in to show me that she had gotten TWO betta fish. I told her she can only keep one per tank and she said she new that. She asked me to help set up their homes. I finished the 2.5g that I had gotten her and asked where the other one was, I was horrified when she pointed to a bowl that was less than 5" in diameter. "I got it at Michaels for $3' she informed me. She told me that the people at the pet store said he would do just fin in it as it was about a quart, the minimum size petco reccomended. I told her as nicely as possible that that would not work out. I had to go into the library for testing today, and the betta in the small bowl was gone. I knew what had happened. :( I just can't get her to listen and I don't know what to do!
