First catch you koi or goldfih in a net allowing it to calm down somewhat prior to doing the scrape, once the fish is calm raise the fish just out of the water hollding it through the net leaving an area clear of the net to take your scrape.Mmathis said:Dave, how do you go about taking a scraping, and do you have to do anything special with the slide (recalling college micro class)? Where are the particular places on the fish that you would want to sample? Do you sedate the fish and how? If you didn't have a microscope, could you get your samples, then take them somewhere to be looked at (wondering how "time sensitive" the specimens would be)? Seems that would be less stressful to the fish if you could take the specimens somewhere without having to transport the fish.
Pd, didn't your other fish also have this milky stuff? Wondering if it's the same thing.
Using a credit card from behind the gills on the body of the koi or goldfish gently scrape along the flank of the fish taking off a thin layer of mucus.
Once you have this release your fish hen with the card speard the mucus on a slide then cover this with another slide and using x60 or above on your microscope look to see what you have under there you'll notice all sorts of wonderful things under there but any parasite will show up as in the slide photos I posted earlier .
pdpond if you would stop thinking people think your not a good fish keeper and listen to what a fish keeper of many years experiance is trying to tell you then perhaps you would get on more with others and learn some important skills .
I for one am not a marine biologist nor do I wish to turn anyone into one I resent that remark but am forgiving enough to help you.
Once you figure out its all about the fish and not your personality then perhaps you'll get somewhere.
There is a whole new world inside that of fish keeping to explore (a truely amazing one at that)and one that will put anyone in good stead for a hobby that will last you years rather than the time it takes you to kee loosing fish were eventually you'd get pissed off with loosing fish and jack the hobby in.....
Instead youd be saving fish and in a few more years be helping someone else in your own situation its not about you, its about the fish you keep who if looked after correctly will in the case of goldfish extend their lives to 40 years and in the case of koi 80+ years "now do you get it " ????.
Turtle mommy no you dont need to sedate but you should have your own microscope which are nowadays quite cheaply bought.
Bresser do a very good microscope that are sometmes seen on sale in stores like Lidl walmart and others that are fantastically cheap to buy .
They also sell some wicked scopes in computer shops etc that connect like my own directly onto my PC, or prior to our break in our laptop, you can if you wish colour your slides thats up to you.
I'm adding a link about bresser microscopes mine is the top one x 40 - x1204 which is more than enough for what you need £59 is cheap not sure on exchange rate :-
