| Hi Renee, sorry you are having such a difficult time! Over time with practice you will get good at this- promise! You can even take samples of your filter mulm and get to see moving life under the scope! But for now I think I can just answer your direct questions. No chilodonella and trichodina and flukes do not cause those white spots. White spots are caused ( of that size) by carp pox, 'budding' anchor worms, some tiny wart like tumors and one encysted and rather rare parasite. The spots of ich usually tend to be smaller and very white in color. And if you can't see any under the scope it is unlikely that we are looking at ich.
All of this points out the real practical side of belonging to a 'live' koi club. In a case like this you could have local people to talk to and ask to come over to help with the microscope work. Not sure where you are, but I'd do a search on the AKCA site and see if there is an AKCA Koi Health person or a club in your immediate area. JR |
