OK I am going to post as Ignorant simply because (please hold off beatings) we killed the class betta. I know NOTHING about bettas so I went by the teachers xerox sheet he lasted 3 weeks. I suck as the pet mom and I feel awful and will (maybe) replace it for fall. I was in over my head and my son feels awful that I failed (considering I raise oscars and an assortment of furries. I found out too late that a goldfish bowl no matter how cute is not adequate, that they require a knowledge I don't possess. I am to blame but to a point is also the teacher whose only requirement was that a student had fish.............................. cichlids and bettas are a far cry in care.
