Am I doing the right thing
 

I have a angel fish (coral beauty) and to percula clownfish a black and orange. I have them in a hospital tank because the angel developed ich. I have treated with meds.
Then was told to use hypo-salinity so thats where im at with it at the moment. But...now the angel has a white spot that looks more like a fungus and still two spots that still look like ich, that have been there for at least 3 weeks. Both eyes look fogged over but still swimming around with energy and eating.
Where do I need to go from here and what does the angel seem to have. I have looked at Lymphocystis but that doesn't explain the ich spots and fogged eyes. Any advice will be appreciated.

Look up brooklynella and marine velvet and see if any pics match.

nether one of those

Update the angel still has ich i got a closer look. But the hypo-salinity treatment has only been started for a couple days. One eye is clear the other looks like it's getting there. Could the bigger white spot be a cluster of ich all in one spot? Ill try and get a photo tomorrow. Seems in good health and doing fine other than the spots.

What meds? What dosage? How long?

As for hypo and ich, how long has the fish been in hypo? It takes a while, and the fish needs to remain there for a good 30 days after you see no ich.

Only 3 days hypo still see ich spots and it was Api ich treatment but that was before I was told nothing but Coopermen works on marine icy. That was 2 weeks.

Angel is doing great still has bigger white spot and 2 small ich spots but both eyes are clear now he is full of energy and eating great

I guess I'm doing it right... Lol. All ich spots are gone clear eyes seems very healthy and big white spot is getting smaller. Now to start counting down the days to start uping the salinity again.

Good to hear!
