For those who would like to see them, you may contact me through email.
Can I put the file on Usenet?

My dad has a 50 gallon saltwater tank, which he monitors very closely.
It's got a large cannister filter, but no wet/dry or protein skimmer.

He generally keeps about 8 fish, tangs, pacific angels, perhaps a pink tip
and a clown fish, nothing too sensitive.

Even though all the tests turn out acceptable - ammonia, nitrates, etc, he
experiences a loss of several fish every now and again. The funny thing,
one or two of the orginal fish have survived many such catastrophes,
including a coral shrimp.

If the tank shows acceptable levels of ammonia, low or no nitrates, and
the water is changed regularly, what could the problem be? Our only clue:
the deaths usually occur soon after he goes out of town, never more than 5
days. During this time, the water temp may rise just a little because he
turns off the a/c window unit in that room. He keeps the tank at 80F, and
the water temp may rise to 84F. Is this enough to stress the fish &
either kill them outright or make them susceptible to disease?

We've ruled out contaminated new fish as a cause, anyone testing the tank
finds it in pristine condition. THe setup is about 9 months to a year old
now.

I'd appreciate a response.

Question 2: Why won't my bettas breed? Next time...

In my 10+ years of keeping marine fish and inverts, I found this to be a
most frustrating problem. Marine fish that look and behave normally turn
up dead the next day or waste away and die. I have seen this particularly
with angels and tangs which in some cases do fine. (I won't even discuss
butterflies) I have not been able to explain these sudden deaths either as
the water quality is always fine and the fish eating. Since I usually
don't see any external parasites, I have assumed that an internal infection
is the culprit and that this is either due to the susceptibility of marine
fish to these organisms and/or related to stress related factors that are
involved in capture and shipping of marine fish. Previous exposure to
cyanide is one obvious factor that is not apparent when examining a fish
prior to purchase.
In my experience there are 2 groups of marine fish that seem to not be
affected by this type of problem and generally do very well in most marine
tanks i.e all hawkfish and damsels. Obviously, there are those net readers
out there that have fish that are exceptions to the sudden death phenomena
under discussion and in fact I have had many blue, yellow, sailfin tangs,
flame,coral beauty, dwarf angels, etc. that have thrived for over a year
but I have also had these fish that were doing fine one day then dead the
next. Last week I lost both a flame angel and pygmy angel on the same day
from my otherwise great reef tank. In discussions with a few other reef
netters they reported similiar experiences in their tanks in fact we have
commented that the inverts are much more reliable and long lived in
properly set up reef tanks than fish. To me this makes me, once again,
return to the philosophical discussion of keeping animals (in this case
fish) whose survival and quality of life cannot be guaranteed.
Mark, sorry I don't have a solution for your problem other than this kind
of thing just happens with marine fish (regretably)
