Symptoms and Treatment
How has your betta fish's appearance changed? He has a white spot on his head and discolorations on the right side of his body that look similar, as well as some underneath his chin. At the very least I am sure the one on his head was not there when I got him on 11/27.
How has your betta fish's behavior changed? I haven't had a chance to determine what his normal behavior is. He seems active, still has interest in eating, but sometimes he whips his tail at items in the tank. Occasionally he will go to the bottom of the tank and rest there vertically with his head towards the bottom and his tail up.
When did you start noticing the symptoms? He has been whipping things with his tail for a few days now. I noticed the white spot on his head last night (11/30).
Have you started treating your fish? If so, how? Last night I did a 100% water change, rinsed everything in the tank with the hottest water that would come from the faucet, and wiped the inside with a warm washcloth. I then added new water from the faucet, added water conditioner, and three tsp of aquarium salt to the tank, added the heater, and acclimated him.
Does your fish have any history of being ill? I just bought this fish. He appeared fine when I bought him.
How old is your fish (approximately)? I don't know, it depends on how old he was when I bought him.
