      Kohaku has lost buoyancy, 3 months now. Looks healthy

      My kohaku, Blondie, has been in my pond for 20 years. She seemed to lose buoyancy in early July, but otherwise has remained healthy. If there's the prospect of food, she comes swimming off the bottom and circles the pond. If it turns out there's no food or she gets fed she returns to the bottom, exact same spot (she's worn the algae off). Her fins are never clamped. She is strong. I've checked out her skin, but there are no problems, not even on her underside. It's like she accidentally swallowed a pound of buckshot. When not swimming hard, she just drops to bottom.

      All the other fish are fine. No new fish have been introduced into the pond in 6 years. Pond ph is 7.2. Water quality is fine.

      Oddly, this same thing happened last year, but I can't remember whether it was her or my showa. I was traveling and didn't pay it much mind. Within a month or so the fish was back to normal. Can anyone solve the mystery of the sinking fish?

      Likely a swim bladder issue. I have one who acts very similar. Swims like a bat out of hell, actually breaches all the way out of the water and then settles back down. We are going on year two like this. I don't know how long she will go on but she eats and seems fairly healthy besides not swimming normally. I bring her inside in the winter b/c she does tend toward ulcers in the colder months b/c she is sitting on the bottom of the pond so long (food for thought). This is not curable if this is what yours is suffering from.

      I was afraid of that, but thank you for enlightening me, ademink. At least I don't have to worry about cold weather causing ulcers. I've noticed that when she dives, sometimes air bubbles escape her body. I might try water wings...

      lol I've tried to think of a variety of things. I have decided as long as she is eating and seems interested in being alive, I'll let her live.
