I don't really know enough about sal****er fish yet but if it's similar
to freshwater then yes it could be ich and your pyjamas just may not
have any stress in their lives which could cause them to develop it. The
other fish may all have been more stressed by moving and therefore
succumbed to it.

With freshwater tanks they say that ich is in a lot of tanks but so long
as the fish aren't stressed by bad water, moving, fighting etc. then
they may lead long, healthy lives.

Aren't there some sort of shrimps that might clean the ich parasite off
affected fish?

Another suggestion for freshwater fish is to raise the tank temp to the
upper limits of normal as the ich eggs don't much like that. An
accidental chilling can cause an outbreak too. Does this apply to salt
water fish as well?

Sorry no answers, just more questions.

Hi. I've lurked but haven't posted in a while.
Can anyone give me some suggestions for this recurring nightmare?
I have a 25G reef, just shrooms, polyps, zoos and a great looking
frogspawn. The corals have been doing very well, almost no casualties.
The fish on the other hand haven't been so lucky.
Most of my fish have at some time or another succumbed to what I
believe to be ich.
The curious thing is that some fish get it and die and others don't.
Example, my two PJ cardinals have no ich on them but my recently
aquired six line wrasse is starting to get some.
I've already lost two clowns and two clown gobies to this horror.
Can this really be ich if the cardinals don't have a trace of it? It
does look like the pictures i've seen. Maybe it's because the
cardinals stay near the top of the tank and all the others like to hang
out close to the rocks and coral?

Any suggestions as to what I can use without damaging my coral? I
don't have a quarantine tank...

Many thanks...
