Symptoms and Treatment
How has your betta fish's appearance changed? Light blue area on fin.
How has your betta fish's behavior changed? Lethargic, loss of appetite, sits in one spot
When did you start noticing the symptoms? A week ago
Have you started treating your fish? If so, how? No, just removed her today when I noticed the color change on her anal fin
Does your fish have any history of being ill? No
How old is your fish (approximately)? Not sure, I got her a few months ago and she came to me full grown.
A week ago I noticed she was acting strange, she would stay in one spot, was barely eating, not competing for food like she normally does, etc. After that went on for two days, I isolated her in a breeder box in the tank. She seemed okay, no visual signs of distress or illness, so after 48 hours I put her back into the tank. She had still been acting strange, sitting in one spot on top of an amazon sword leaf. She would come over during feeding time, but go right back to her spot after eating.
This morning, she was still on her leaf, and I was going to take a pic of her and post here about her "depression" and I noticed a light blue patch on her anal fin, so I promptly removed her.
I'm worried about her, but I'm also now worried about the other 7 fish that are currently in with her. (One female has been out for a month due to breeding)
