White or black ich? (I ask, because black ich is quite
common in tangs - not in most other fish)


White. About 20 white spots randomly spread over his body.

MIGHT work. I had one tang that refused to beleive a Lysmata
wurdermanni was not actually a Lysmata amboinensis. Kept going up to
it like he expected a cleaning. Poor shrimp had no idea what was
expected of him.
Not I have the opposite - new tang, new peppermint shrimp - peppermint
shrip actually wants to pick at the tang, and the Tang wants no part
of it - but DOES let my skunk cleaner clean him.


So peppermints are not as good, right?

Depends on the individual. Some peppermints will do just as good a job,
but most won't do any cleaning (YMMV)

OK. So, the ich is small white spots. Sounds like cryptocaryon.

So, hate to tell ya, the CORRECT treatment is this-

take ALL fish out of the tank for 1-2 months. Take the infected fish,
give it a dip in freshwater buffered to PH to match tank water, with
formalin and copper sulfate added. I usually add some methe;yne blue to
help boost oxygen, since it is also an anti paraiste and won't hurt.
After the dip (dip for about 7-10 minutes) put fish in a seperate tank
and continue treatment with copper sulfate until all symptoms are gone.

Alternate if you just plain can't take all the fish out for a month or two:

treat sick fish with dip as above, and add garlic to main tank and cross
yer fingers that fish does not get re-infected.

I have also had good luck with Chem Marin's "Stop Parisite" product.
Dunno if it was merely a placebo effect or not (ie: I had kille dthe ich
without it anyway) but I did option #2 above, and then added this stuff,
and the problem was resolved.
