Pale/White blotches on fish

bingo I found u

If it is columnaris, Kanamycin would be the best choice for an antibiotic. This disease will manifest rapidly and kill the fish within days if not treated quickly. Good luck! It is treatable though, and fish recover well. I think we have all had this problem at some time in our fish hobby life's.

Need some help with this situation....

got the same problem, can you help?

I have been thinking

Columnaris and Fungus are hard to distinguish the difference between sometimes. But since you said the skin is discolored as well, I am going to take a chance to say that it is columnaris.


Columnaris

Description:
Despite one of the disease's names, Fungus, this is actually a gram-negative rod bacterial disease. Columnaris bacteria will typically attach themselves to a fish's head, mouth, lips, or inside the mouth. Columnaris has different possible appearances:

• The mouth "fungus" is commonly called cotton-mouth because the fish's mouth seems to be covered with a thread-like cottonish substance. Since the initial leisions look somewhat like cotton, columnaris is often confused with true fungus. Note that when examined very closely, fungus has distinct hair-like filaments which shoot out, whereas columnaris is more like fuzz or lint.
  
  
• Columnaris usually affects the mouth area but can also appear as yellowish-brown, white, or grayish-white spots on some part of the head, fins, gills, or body which are usually surrounded by a reddish area. This type commonly takes what is known as a saddleback pattern on the fish's body.

Labyrinth fish and Apistogrammas are highly susceptible to this disease. Prevention includes keeping the water very clean by performing frequent water changes. As with any disease the fish is more susceptible to contract columnaris following stress. Also keep in mind that bacteria bloom in higher temperatures.

Treatments include:
Malachite green (except for fry), salt, Melafix, or antibiotics as a last recourse (such as Spectrogram, Furanace, or Sulfa-based products).

not sure how to link my post:

Columnaris /Flexibacteria anyone know a pacpac2 ? Could really use his help,

For columnaris, try Triple Siulfa or OxyTC . Kanamycin is not the best choice for Columnaris.

If ths is columnaris, can even try dipping in copper sulfate but need to carefully/precisely prep dipping solution. Difficult at home unless have right apparatus and ingredients.

I believe I mentioned protozoan Chilodonella cyprini on other post. Google for info and images for comparison. Should be able to find treatments as well.

Good Luck!

Oh, what is your usual pH???
