Anyone with experience with velvet/oodinium?

Some of you may recall I posted several months ago regarding some
puzzling fish deaths in my 165 gallon South American tank. First, my
prize Uaru died. It acted as if it had something stuck in its throat,
but my autopsy did not discover anything. Then a Severum died, and
various small white threads could be seen trailing from its gills. The
best guess then was gill flukes. But I was skeptical of this explanation
since only one fish seemed to be affected at a time.

After reading an article in the American Cichlid Association's recent
edition of "Buntbarsche Bulletin" about a researcher's struggles to
diagnose and treat a disease plaguing his wild caught Julidichromis, I
have deduced that my problem is definitely the dinoflagellate oodinium,
which is commonly known as velvet. Never thought of velvet because I
thought its classic symptom is supposed to be rust-colored velvety
patches. However, after consulting Baensch, I discovered that it can
also appear as bluish-gray patches on the size of the fish. I purchased
four small Uaru several months ago, and one of them had this patch on its
side (and still does). However, as I have also discovered now, the fish
can be affected by this parasite without ever showing anything on its
skin. In my case, the fish were essentially suffocated by a massive gill
infestation.

In any event, I am now treating as for ich -- QuickCure (formalin and
malachite green), raised temperature (around 87 degrees), salt, low
lights. No real progress so far, and looking over old posts this seems
to be a difficult disease to eradicate. Does anyone have any advice or
experiences to share regarding this nasty and sneaky parasite?

I had a similar "mysterious death syndrome" a year or so ago. It was
hitting one fish at a time and there were no visible external signs.
Like you, I tried the formalin/malachite green method with no luck. I
later tried "Fungus Eliminator" and it seemed to stop the deaths and
the fish have been healthy since. Your guess would be as good as mine
if it was the ingredients in the product or the fact that it is mostly
salt. It could be a combination of both but I did not follow the
directions and repeat after 4 days. Instead, I did 50% water changes
for the following 3 days.

Good Luck

You should ask Frank....he hangs over at alt.aquaria....I will crosspost
this. I wish Frank would hang on a few other groups too...like this
one...He is fairly good on ailments and treatments....

Racf,

Thanks. Thought your name choice was a variant on the abbreviation for
this group (rafc), but I see from your other post that that is just a
coincidence.

Not sure what rafc is, but I started using RACF as an IRC handle in
computer security groups back in like 1996 or so, where it made a lot
more sense....than in aquaria groups. I used to use my real name in
Usenet, but I quickly learned that it was a bad idea....I wish the
Internet was not so .......... so as to use my real name again.....it
works fairly well...

Any luck yet?
