Symptoms and Treatment
How has your betta fish's appearance changed? Medea has become pale and greyish instead of her normal vibrant blue. I've seen stress-stripes sometimes. Her front section is very bloated (no raised scales) and she has a number of small bumps on her face and neck.
How has your betta fish's behavior changed? It hasn't - she still eats well and swims actively.
When did you start noticing the symptoms? She has had the little bumps for weeks now, but the bloating and colour loss has become more noticeable in the past three days. I have done a water change, but it did not change her appearance.
Have you started treating your fish? If so, how? I'm fasting her today. I normally fast on Sundays too. I'm giving my CRS colony to a friend ASAP and converting their tank into a hospital tank for her. I'm considering an epsom salt treatment.
Does your fish have any history of being ill? No, apart from the little bumps which I did post about when I saw them and got no response to.
How old is your fish (approximately)? Probably about a year, assuming she was 6 months-ish when I got her from the petshop.
Please help me. :( What treatment should I use and what is her affliction?
