Raised White Spots

[Fintastic!]

Hi Welshweeks, he's not so good. I hate to say it but I'm thinking of euthanising the poor thing. One of the spots has grown quite a bit over the past couple of days. It's white with hair-like bits coming from it.He's not as interested in food and sits at the bottom with his fins and his mouth going.

I'm not sure if anyone is still reading this but I THINK I'VE FOUND THE ANSWER!!!!!!!
After many net-trawls.

Has anyone heard of this? Not to be confused with columnaris but looks similar. The difference being hair-like growths with little ball-like tips coming from the cotton-wool-like spot. It sounds just like what Miguel has.
It says it grows in aquariums with lots of decaying matter. This has me puzzled as I water-change weekly without fail and my tank is kept clean. I did have a pepper cory disappear a couple of months ago. I don't know, I'm grasping at straws. I don't know what to do as he has this almost two weeks now. The Protozin didn't make a difference as it isn't a fungus but bacterial apparently.
What to do??
The article recommended methylene blue baths. What is that
I'm at a loss. Is it too late to treat him

I found these instructions upon searching through google. Maybe they will be of help to you

Prevention or treatment of fungus or external parasitic protozoans:
(a) Remove carbon filter and continue to operate with mechanical filter media throughout the treatment period.
(b) Add 1 teaspoon of 2.303% Methylene Blue per 10 gallons of water. This produces a concentration of 3 ppm. Continue the treatment for 3 to 5 days.
(c) Make a water change as noted and replace the filter carbon at the conclusion of the treatment. As an aid in reversal of nitrite (NO2-) or cyanide (CN-) poisoning of marine and freshwater aquarium fishes:

(a) Remove carbon filter and continue to operate with mechanical filter media throughout the treatment period.
(b) Add 1 teaspoon of 2.303% Methylene Blue per 10 gallons of water. This produces a concentration of 3 ppm. Continue the treatment for 3 to 5 days.
(c) Make a water change as noted and replace the filter carbon at the conclusion of the treatment. parasite protozoans." For use as a dip for treatment of fungus or external parasitic protozoans and cyanide poisoning:

(a) Prepare a nonmetallic container of sufficient size to contain the fish to be treated by adding water similar to the original aquarium.
(b) Add 5 teaspoons (24.65 ml) per 3 gallons of water. This produces a concentration of 50 ppm. It is not recommended that the concentration be increased beyond 50 ppm.
(c) Place fishes to be treated in this solution for no longer than 10 seconds.
(d) Return fish to original aquarium

Thanks for that Rolltide, much apperciated! I read to leave the fish in the 'bath' for 20-30 minutes but the concentration might be smaller in the article I read. I'll go on a hunt for the mb soon.

Miguel is gone to fishy heaven.
