Symptoms and Treatment
How has your betta fish's appearance changed? There is a small chunk missing from her anal fin. The edges are light gray and there's a white hair-like thing hanging down that is about the length that her fin usually is. A little dent near the back of her anal fin is just now appearing. The edges of her anal fin are a little lighter than usual. Her back fin clamps more than usual, but it doesn't remain clamped for long. It has only happened a few times.
How has your betta fish's behavior changed?A wee bit less energetic than yesterday and the day before, but that much energy was a bit out of character for her.
When did you start noticing the symptoms? About ten minute ago. Dent appeared while writing this.
Have you started treating your fish? If so, how? By the time someone replies, I will have probably given her a 100% water change.
Does your fish have any history of being ill? She had mild Ick when I first took her home from my boyfriend's house. It went away very quickly.
How old is your fish (approximately)? 6-8 months. She's small and really energetic.
