Symptoms and Treatment
How has your betta fish's appearance changed? No. His bite did not result in physical injury.
How has your betta fish's behavior changed? This guy was never very active to begin with. He was certainly not a very dominate fish and I am assuming he would have died in nature. He is very sluggish now. He has no interest in other fish. Generally hangs out at the bottom of the tank. He seems depressed to me.
When did you start noticing the symptoms? About a week ago. The 2 Betta's were together in a tank for literally no more than a minute. As I was getting the other tank ready, my wife said that one of them bit the other, and I rushed to separate them.
Have you started treating your fish? If so, how? I keep his tank away from the others to help him stay calm.
Does your fish have any history of being ill? No
How old is your fish (approximately) ? I have only had him for about 3 weeks
