I hate to burst anyone's bubble, but info on fish diseases comes in all shapes and sizes. I rely on papers I search out using Google Scholar. Just to give you an idea of what you can find. Here is a paper on Ich you might want to check out:

Infection by the ciliate protozoan Ichthyophthirius multifiliis Fouquet, 1876 causes significant economic losses in freshwater
aquaculture worldwide. Following the ban on the use of malachite green for treating food fish, there has been extensive
research aimed at identifying suitable replacements. In this paper we critically assess drug and non-drug interventions,
which have been tested for use or have been employed against this parasite and evaluate possibilities for their application in
farm systems. Current treatments include the administration of formaldehyde, sodium chloride (salt), copper sulphate and
potassium permanganate. However, purportedly more environmentally friendly drugs such as humic acid, potassium
ferrate (VI), bronopol and the peracetic acid-based products have recently been tested and represent promising alternatives.
Further investigation, is required to optimize the treatments and to establish precise protocols in order to minimize the
quantity of drug employed whilst ensuring the most efficacious performance. At the same time, there needs to be a greater
emphasis placed on the non-drug aspects of management strategies, including the use of non-chemical interventions
focusing on the removal of free-swimming stages and tomocysts of I. multifiliis from farm culture systems. Use of
