Fluke tabs apparently fatal to Orfe

Post by John Canfiel » Thu, 28 Sep 2000 04:00:00



I'm not exactly heartbroken that my three *** Orfe are dead as I was going
to try to give them away in a month or so, but I didn't want to see them
leave my pond in this fashion.

My dozen Koi and twenty Koi fingerlings started to flash quite regularly
recently, so I decided I needed to take some sort of action.  Catching and
scraping the fish for microscopic analysis would be ideal, but due to the
plants in the pond, that was not easy(yes, I could drain the pond way down,
but didn't want to).  I tried a massive water change with no luck (water
quality was okay before and after the water change).

Salt was my first choice for something to try and I salted to .03% over a
three day period and I noticed much less flashing, a better appetite, and
they were schooling more.  But still some flashing.  I decided that Fluke
Tabs would be a good protocol for parasites that might be the cause of the
flashing, or as a good thing to do as I get the pond ready for winter in any
case.

24 hours after adding Fluke Tabs, all three Orfe died suddenly and without
any apparent signs of distress.  The Koi are not eating now and are very
lethargic -- maybe this is normal behavior with this drug.  I was wondering
how the Orfe would do with the Tabs, now I know... not well at all.  Nowhere
have I noticed any statement that Fluke Tabs and Orfe don't mix well.

One, of the two, ingredients in Fluke Tabs is an organophosphate.
All organophosphates are fatal to Orfe and Rudd. - source Dr. E. Johnson
DVM, on page 85 of his book Koi Health and Disease. ( a "must have" book
for koikeepers, IMHO )

Different folks have varied (negative) results with Fluke Tabs - "this
is a very harsh drug" - to quote the manufacturer - and its toxicity is
also dependant on water chemistry and temperature (*much* more toxic at
high pH and low GH.)It is not a medication I turn my back on after
administering. Doc Johnson's dosing schedule for Fluke Tabs -
http://www.koivet.com/fluketabs.htm
though, IME, goldfish have a lower tolerance for this drug than koi, and
should have a 100% water change after 12 hours.

Sorry you had to find out the hard way - - hope your survivors are
improving. Lots of water changes and some salt may help. (hope you
didn't dose this in your pond..... 6,300Gs....)
