My best friend's (since 6th grade) roommate got a betta fish. My friend's not an animal person, but she was very excited about the fish because she knows that I love them. However, I found out that it's kept in an unheated bowl (I don't know the size). I don't know if I should say anything, because I don't want my friend to think that I'm saying that she or her roommate are stupid or bad owners or anything. I did subtly try to hint that they should upgrade his home. I said that it's going to get pretty cold in the winter so they might want to get a heater. I then said more bluntly that it had to be kept at around 80 degrees. My friend said that her roommate had fish before so she knows what she's doing. We live in Vermont and the dorms are heated, but not amazingly so. I'm a bit worried for the fish, but besides that they take good care of it and they have good intentions. What would you guys do?
