Hello, so just received a lot of rain here in So. Cal this past week. Noticed one of my larger butterfly kois swimming kind of weird. I guess best way to describe it was just kind of derpy, using mostly her tail with her front finds tucked. Then started noticing her tail and fins had pink on it. Reached out to some people and thought it might of been caused by ammonia poisoning. Gave her a salt bath yesterday for 10 mins in a 25 gallon tote since i dont have a quarantine tank yet. Put her back in the pond, she seemed better last night, even swam around a bit with her fins out. Did a 20% water change as well on the pond also. Checked on her today and shes swimming like yesterday, front fins tucked in except once and a while she brings them out. But her swimming is kind of derpy, using mostly her tail and then floating on by. Any suggestions? Pond water test PH = 7.2, Ammonia .25 PPM, Nitrite and Nitrate at 0 PPM Heres a video of her during treatment
