Hi everyone, I've searched and tried several different things with no solution or help yet.
I have a 24-30" shiro utsuri that is probably 5-6 years old that stopped eating about a month ago now. We are moving to a new home so they are currently in a 12ft intex pool setup, but he was doing this while in their normal basement pond that they've been in for years. I've tried bsdt shotgun treatments, salt baths, sebactissun, and api ulcer treatments and nothing has worked. I pulled him from the pond while doing the salt baths and checked for an obstruction in his mouth, but nothing there either. All of the other fish are doing perfect and my water quality is really good at the moment with 0 ammonia and fully established filters now.
As a recap of his symptoms, she has red blood vessels, not eating, hiding on bottom or under plant baskets, sometimes clamped fins.
Does anyone have any other ideas or thoughts on what might be going on with this fish? I know it's pretty tough to see in strong detail through the netting over the pond and the reflections, but here are two pictures:
Thank you tremendously for any help!
