Strange problem with fish! HELP PLEASE!

[Dean110592]

Over the last few days, 2 koi and 2 goldfish have started suffering from something which appears very strange! They are swimming very erratically and jerky, they also seem to have a slight bend/kint half way through the body. They seem to act fine, swimming when possible, and attempting to eat. But swimming is a struggle for them and they seem to shake when swimming as appose to flowing (hard to explain). Boyancy also appears to be a problem. No visual signs of infection. The easiest way to describe is it looks like theyve been electrocuted! Any help will be great! Water readings are fine, around 7.6ph, 0 ammonia, 0 nitrite and a smidge of nitrate (normal?) .. the pond is relativly new but all has cycled and all was settled until a few days ago!

An electrical short in any submerged lighting or other wiring will cause behavior such as this.

Ditto what Meyer said. Be careful and get it fixed ASAP [assuming that's what it is].
