I looked around the net a bit and it sounds like your fish has what is called Velvet. Here are some words on it:
Quote:
They appear as yellow or brown dusty spots on the fish. The fish may show signs of irritation and may be rubbing on surfaces in the tank.
Remedy: Quarantine the fish because Velvet is highly infectious. Treat it with copper at 0.2 mg per litre. Repeat once every few days if needed. Do not prolong the treatment as copper can cause fish poisoning.

Velvet looks similar to Ich, but there will be many more small white spots that appear dusty. This Protozoan disease in fresh water environments is caused by Oodinium limneticum and Oodinium pillularis. In marine environments by Oodinium occellatum. The parasite attacks the eyes, fins, gills and skin. The disease may resemble "Ick", but is recognized by a dusty appearance on these surfaces and can have a yellowish color. The fish may attempt to scrape itself against objects in the aquarium, exhibit a loss of appetite or a stressed-rapid breathing. The parasite has a cyclical life span and can only be affected by treatment during the free-swimming stages of the cycle
Treatment: In most cases the use of a Copper Sulfate or Copper Formalin based medication should be able to clear most parasite outbreaks. I recommend Copper Safe, or Maracyn. In severe cases, it may become necessary to exactly determine the type of parasite, so that a more targeted medication may be prescribed. There are various commercial remedies on the market which commonly come in either chelated or non-chelated formulas. Chelated formulas are easier to administer, but may not be as effective as non-chelated formulas with certain outbreaks. Whichever brand you choose, be careful to follow the manufacturers directions precisely. The parasite usually leaves an open wound once it leaves the host to reproduce and in many instances a secondary bacterial or fungus infection may occur. It is always prudent to combine an antibiotic remedy with the parasite treatment to prevent further complications.
Thermal Therapy: In aquarium environments with warm water species, raising the aquarium temperature to 90º for a period of 5 consecutive days may also be effective. Do not use thermal therapy on fish sensitive to warm temperatures, as it will only lead to increased biological stress.

Symptoms: Clamped fins, respiratory distress (breathing hard), yellow to light brown "dust" on body.
This disease has the appearance of a golden or brownish dust over the fins and body. The fish may show signs of irritation, like glancing off aquarium decor, shortage of breath (fish-wise), and clamping of the fins. The gills are usually the first thing affected. Velvet affects different species in different ways. Danios seem to be the most susceptible, but often show no discomfort. This disease is highly contagious and fatal.
The best treatment is with copper at 0.2 mg per liter (0.2 ppm) to be repeated once in a few days if necessary. Acriflavine (trypaflavine) may be used instead at 0.2% solution (1 ml per liter). As acriflavine can possibly sterilize fish and copper can lead to poisoning, the water should be gradually changed after a cure has been effected.

I hope all goes well.
I used to keep albino corries with white sand substrate. And I must say, the whiteness really brings out their eyes. They also turn pinker when kept like that. Like they have a fullbody blush, very cute.
