I have told her to get him a tank, I hope I have her convinced.
His fins aren't clamped and he only gets two pellets every other day and they are small, but he will rarely eat them.
Yes we use water conditioner.
As of now he is swimming happily around his small vase.Her other betta, Hank, (where she gets these names I have no clue) Has an even smaller space to swim and I tried to get her to at least put him in a bigger vase. She is going to buy a bigger one for him tomorrow. But Hank has never done these things.
