Milky white patches sounds like Flavobacteria columnaris, a bacterial infection.
It can be treated with most aquarium antibiotics.
Other things that contribute to this disease: High nitrates. Keep the nitrates under 20 ppm with frequent water changes.
High temperatures. Not much you can do when the fish thrive in much warmer water, but for fish that are OK in cooler water then you might reduce the tank temperature by 1-2* per day to about 75*F. (1*C per day to 24*C). Do not do this to Clown Loaches, or other very warm water fish, though.
High level of organic matter in the water. Thorough gravel vac, perhaps several. Remove as much organic matter as possible from the water.
It goes by several common names.
Saddle Disease (Often starts on the dorsal surface of the fish)
Columnaris (from the Latin name)
Mouth 'Fungus' it is not a fungus, but may look like it.
Fin Rot- it is one of the bacteria that can cause fin rot.
38 tanks, 2 ponds over 4000 liters of water to keep clean and fresh.
Happy fish keeping!
