Fish Health - Mechanical Fish
Fish appears to be mechanical
- it swims like a clockwork fish, with head and tail having lost their
coordination.
This happens when a fish has broken its back, due to
sudden shock or sudden vibration - the fish has engaged its flight muscle,
which in most cases is the cause. Koi very really use these muscles unless they
are being chased by a net or a predator, or even spawning.
Other causes
are bacterial infection of the dorsal muscle, and or the head,
kidney.
There is no know treatment I know off> However, most fish
survive long periods, some even
years.
