When was the last wet item added? History of fish?

I had something similar happen to a purple tang... your's looks like mine when it first started. It eventually healed on its own. This was three years ago the the PT is still going strong. Not sure what my problem was... or if you have the same thing.

I hope this picture is slightly better very hard to get him turned on his side where the patches are visible

I've had him approx 3 months his only tank mates are a pair of clowns and a cleaner shrimp

Params are:
Nitrate 0
Phosphate 0
Ph 8.35
Ammonia 0
KH 8
Mag 1350
Cal 420
Salinity 1.026

Test regularly and also get icp tests done with no swings. Running triton method. Tank has been running for 2 years. Heavily stocked with lps and some softies.

He's in a 85gal tank and is approx 2.5"-3"

Eating perfect no change in breathing or swimming acting normal

Is it possible he could have been stung by my Nem? I've a long tentacle approx 10" when fully opened in the day.

Other fish have no signs of any spots on them. I didn't qt this fish my lfs did for 6 weeks. There treatment is copper

I run ozone and skim heavily with a deltec sc1456 also running a carbon reactor which I plan on taking out as I have only started running ozone.

Thank you

elFloyd,

It actually looks similar to yours but the white patches haven't gone as bad yet. Would it be the Nem do you think? It's strange because he's completely normal and definitely has not lost his appetite

I really have no idea what cause my issue. Fish acted fine... problem cleared in 4 - 5 weeks. Wish I could help more.

Was there any raised lumps on your tang
