There really is no such thing as skinny disease, it's just a misuse of wording. Skinny, like emaciation, is just a symptom of a possible internal infection, either bacterial or parasitic. Most people just call that skinny disease though.
It's easiest to treat for internal parasites when you 1st get the fish. When they become emaciated, it is sometimes too late. Prophylatic treatments of praziquantel and levamisole is a very effective preventative.
Internal bacterial infections are usually the result of poor water quality or internal injuries caused from osmotic shock. Osmotic shock is when water chemistry changes are too sudden for the fish to acclimate to. This usually happens when fish are moved from one tank to another, like when you buy a fish from the LFS and put it in your tank. It can also happen when a large water change is done, where the tap water chemistry doesn't match the tank water. A TDS meter reading is probably the easiest way tell if the water chemistry matches. KH and GH test kits will also help determine the water chemistry.
