Symptoms and Treatment
How has your betta fish's appearance changed? About 3 weeks ago, noticed white patch on head, near gill. Behavior normal at that time. about a week ago, started hanging out mainly at bottom of tank, but still eating. Last two days--stopped eating. Lays on side breathing hard. Clamped fins. White patch is different and has either spread or she's fading for another reason. White patch doens't seem fuzzy.
How has your betta fish's behavior changed? See above
When did you start noticing the symptoms? About 3 weeks ago saw spot, a week ago she started swimming less,
Have you started treating your fish? If so, how? Did a round of bettafix after first noticed white spot. White spot got smaller.
Does your fish have any history of being ill? no
How old is your fish (approximately)?at least a year old (have had her for a year)
When the original white spot showed up, I did google and decided that it really didn't look fuzzy. I've had fish with ich in the past and knew it wasn't that. No visible parasites. The tank does not have a light fixture attached, so it's hard to notice physical changes from day to day, but as recently as when the spot first showed up, she was still acting normally. She did not originally have a heater--I put one in about 2 weeks ago (one of the very small ones that is not glass) then she spent all her time butted up against it. I figured it wasn't getting it warm enough, so I put a glass heater in about 3-4 days ago. It has only been since then that she's really been sluggish, stopped eating, and had clamped fins. All water parameters are from earlier this evening--I did about a 75% water changed a little while ago.
Thanks in advance for any advice. I have petco/petsmart nearby and can go for medicines in the morning.
