The scope at below is advanced. A simple monocular scope will do.

Scope basics:

Glass optics are best. Up to 400 x magnification is perfectly sufficient. A mechanical stage is good. A built in light source is necessary. LED illumination is cooler and will kill specimens more slowly.

Warranty work in North America is recommended, lest you should have to send the scope to China for service. Scopes under $200 are often quite adequate for Koi parasite work.

How To Use A Scope

(1) Turn on the power
(2) Start with the lowest power optic
(3) Close or reduce the iris diaphragm!

Here are some basic points concerning microscopy:
Only live specimens will have parasites on or in them. A dead fish cannot demonstrate the ciliated protozoans or flukes. Immediately after death, the tissues become suffused with saprophytic bacteria which will resemble a protozoan infection. It is essential that if you take the time to fire up the scope, you know what you can or cannot expect from the cadaver.

Dead fish CAN exhibit intestinal parasites, and if killed then preserved by refrigeration or freezing they CAN be used for bacteriological investigation.
