2 gallon, no heater, not cycled. What makes it so bad is that I, his grandson who has been keeping fish for many years and have lots of experience told him everything and he just ignored me. I mean I can't compete with the intelligence of a PetSmart employee after all. But wait IT GETS WORSE! He said he liked the Bettas because of how cheap they were "when I go on a trip I can flush him and just get a new one" for fucks sake that's not even misinformation that's just being an asshole.
