thanks for the help!
yes he rubs but the tank is at 86F and that should be around the temp ich is killed (86f or 88f).

there are also no visible parasites on the body or fins...only the white patches of cotton like fuzz on the head/cheek.

to me this seems more like fungus or a bacterial problem but im not good with this stuff

i Think, the water source itself is ok, as i use it on other tanks with discus, another aro and others, no problems elsewhere.

just the water in This tank is bad. there was also planaria in this tank which points to water but no other tanks show anything. there is something about this water or fish thats just not right

my Guesses:
sw particles in the water made water bad (changed 2X a week w/ 1 of 2 filters cleaned alternately)
cross contamination from another tank
i just stopped green water/sun light in the tank so maybe as algae died water went down or parameters changed?

again thanks for your help, i just dont want anything to happen to this fish and scared beyond belief i might lose this fish if things keep going this way
