another thing i've noticed too, is that the older koi now just seems to be hovering around not doing anything, with it's mouth near the surface of the pond just constantly opening and closing. The only time it now swims around is when it shoots of to rub itself against the pond.
I've had a look at the older Koi (the younger ones are a pain in the neck to catch!). I can't see anything out of the ordinary on it. The only other thing i will add is that it doesn't seem to be eating like it did before, it used to be one of the first ones to the top to get the food, the last couple of days it doesn't seem that interested.
There's been a couple of times this morning that i saw it rub it's side against the bottom of the pond and then it suddenly shot up out of the water and back in again.
I've noticed in the last few days that a couple of my young ghost koi and one of my older koi have started rubbing themselves against the side of the pond, almost as thought they've got an itch if you know what i mean.
roughly how long are Ghost Koi supposed to live for?
I had one in my pond that was about 10 years old. My dad had it in his pond to start with, then i've had it in mine for the last 5 years. I found it dead today, floating at the top. I can't see anything rong with it and it was swimming around fine yesterday.
