So our pond guy has been out today and done a scrape. He pulled out the new female koi and a few of our own fish. He found nothing. Not a parasite in sight.
So…. I think that maybe our own fish had an adverse reaction to the treatment put in the pond while we were away. The fact that the filter wasn’t running properly for two weeks, due to low water levels.
So they were put in a treated unclean pond. Would you like it? Nope. So fingers crossed now that everything has settled with the water etc, that the fish will all calm down. Things improved with the sansai, so I think I will continue down that road. At least it will help with the red skin.
So with the ph swinging from 7.5 to 8 and a slight ammonia high with feeding. I think this has caused the bulk of the problems.
Will try and get everything back to tip top condition.
Keep you updated.
