The yellow one has what looks like a patch of raw skin and the black one and marble one have what looks like peely skin...??

Had to include this one for levity as this little tetra kept darting to the camera screwing up the focus on about 20 pics.

First off, lower your temperature. Funguses love warmth, and it will grow faster that way.

Then, treat with melafix. You should see improvement quickly.

OK, i thought it might be fungus...what do i do if the ich comes back then if i cant treat with heat?

Tough call. You may have to look into an antiparasitic medication.
