To describe the infected tanks:
the first tank which used to have the F cingulatus (its been cleaned and
they've been euthanized)
its a 40 gallon tank that I kept mostly fish from the okeefenokee trip this
spring, along with som fish from my first collecting trip to Tampa in march
(the one with the gator). No problems for at least 2 months until I went to
Tampa again and added a few fish...
Another tank is a tank that has a couple mummichogs and some mollies from
Georgia I collected last year. I've had them in fresh water for months. I
collected more mollies in Tampa in June and now, they too have white spots.
A second 55 gallon tank has kind of the left overs - fish that I don't know
exactly what to do with, but I don't want to euthanize. In here I have
swamp darters from the okeefenokee last year, Fundulus notatus from Kentucky
from the last couple of years, a couple of Siamese algae eaters that got too
big and quit eating algae. The fish had been fine for some time until I
added a couple of mollies fomtampa to tackle the hair algae. Now the f
notatus have white spots, as do the mollies.
the fourth tank is the oddest and most disappointing. I have 2 tanks of
southern red belly dace fry. One tank is a 55 and is offspring of fish from
Kansas. they are not infected. Right below this tank, is a 29 gallon tank
with offspring of local SRBDs. They are infected, quite heavily. The F
cingulatus tank is on the same level as the infected SRBD tank, but it's 1
tank over. the tank in between has adult SRBDs which do not seem to be
infected.
Thus far, I have about 16 tanks which receive similar treatment, but are not
infected. I do not have mollies in any of the other tanks, but I do have
fish from my second Tampa trip in several other tanks (all watched closely).

I've been meaning to pipe in on this all along... Just been too danged busy.
I'm now 99.9% sure that my problems back a few weeks ago (the indicative
disease looked like lymphocystic conditions) were spoiled food. I changed
everything back the way it was before the holocaust began (besides some
nitrate issues). Added two new "big box stressed" rainbowfish 6 days after
the final deaths and saw zero occurrence of _any_ type of disease,
parasitism, mortality. I then added four new rainbowfish two weeks later,
again, no problems.
The only thing that changed was _the food_ in the systems that went down.
In the 30, where there was a stray voltage problem but did not receive any
of the tainted food, all problems ceased after the tank was at ground. Any
disease went away, there was zero mortality, even tho many of the animals
looked like they were walking along at death's gate.
The last thing I have yet to try is to establish some fish for a month
without any issues, and then begin feeding the plankton-o-death. I'm going
to hold off on this unless Sally's wants to be stinkers about sending me
some new food or some type of "one to one" compensation for their spoiled
product.
Always something to consider. Fish do not "just die" nor does disease "just
appear".
However, from what I've been reading, food (unless you have the unfortunate
problem of multiple spoilings) doesn't seem to be your problem Geoff. What,
if anything, changed prior to the outbreaks? Did you start running the air
conditioning, which can lead to a lowered available O2 level in the tanks?
Did you rewire an electrical line? Did the presence or behavior of new
additions (that were stressed from wild capture stress) stress out the
established fish?
I guess what I'm trying to illustrate here are the strangest things can
cause the greatest problems.
