C.Loaches with red gills

Had a nasty outbreak of ich/white spot, which only affected the clown loaches. I am treating with salt (2tsp/gallon) + temp (82F). The Ich appeared to get worse for a week (I know - it's supposed to) and 3 days ago finally dissappeared from the fish. Salt and temp are still high to eliminate the parasites in the water.

The 2 young clown loaches (about 1 inch long each) now have bright red gills. It looks like the gills are inflamed inside, and can be seen through their thin skin.

They are not gasping, are behaving happily as they did before they got Ich in the first place.

Should I be worried? Are they ill? Or is this just what gills look like after ich?

Thanks for any advice

Dave.

water parameters have been checked very regularly during the whole thing. They have remained stable at:

ammonia 0
nitrite 0
nitrate 30 (tap water is 20-35 round here - and the fish seem to be used to this level)
PH 7.8

I will see if I can get a pic

cheers

Will keep up the treatment, thanks for the fish advice.

Since I am already more than half way through the salt treatment, I am loathe to suddenly change tack. I guess one option is to continue to treat the main tank with salt, but remove the 2 clown loach to a hospital tank and treat them with something else.

However - I have researched the salt thing a lot, and there seems to be a massive consensus that salt is OK with Clown Loaches. I have not looked into other medications, so I have no idea what risks go with them. I am also concerned about the added stress that moving the fish to another tank might have when they seem happy at the moment.

Have other people had red gills when using salt for ich? did the fish go back to normal after removing the salt?
