Just an update for folks that are interested.....As it turned out I had a bad parasite infection....probably due to some rescue fish that I took in without quarantining them (I know.... I am learning slowly)..... so I bought some Pond Prazipro and treated the pond so I went from my Koi being nose down and tail up and blood red fins to now after three weeks, they are back on the horizontal and fins are almost back to normal.....what was weird about it was until I treated the fish I never saw any signs of parasites, but after I treated them started to see bumps and things hanging off of them, so I am guessing that it caused them to evacuate the host. And no I am not a Spoke Person for Prazipro..... I actually found out about it doing searches for sick fish on this forum......but thankfully it’s working.....thanks for everyone help and concern.....Jimmy
