twice i've seen at the fish store, 2 bettas in one cup. some crude person must have thought it was funny. i told the worker so they could seperate them...but neither had battle scars, nor were fighting when i saw them...do you think you could buy 2 that you might happen to find like this? i seen this again at walmart today, and the two seemed to be peaceful together, and neither had torn fins or anything. but since there wasn't any workers around, my bf took one of their nets and put the betta into a empty cup on the shelf.
i get so tempted to buy these ones, and try to house them together....but i don't want to take the chance.
