My poor blue betta fish. She was always the most aggressive one in the tank. Always the bully, now someone has bullied her back really badly. I have had this sorority since February of this year. I used to have 4 fish but, one died due to sickness, she wasn't eating, and always bumming out at the bottom of the tank. She had a tumour growing on the side of her.... poor fish. Not much I could do for her. :( Since the agression was way too much with only 3 fish.. I had purchased two more fish. I re-arranged everything, and established the sorority again. It has been going good for about a month now. Everyone seemed to get along, but I guess not.
So, there's my situation... Help?
