Re: No clowning around (like I'm sure I'm the first to come up with
that), Dimilin in dips – 04/1/08
I had looked at that link
(many times), couldn't make any inferences. Unfortunately the clown died
the day before yesterday. He had no tail left, think he suffered too
long and was beyond return.
<Agreed>
Just before he died I dosed
the QT with Jungle Parasite clear (Praziquantel, Dimilin, Metronidazole,
Acriflavine). I really wanted just Metronidazole but I couldn't get any
at the time and picked up the mentioned out of desperation. Which leads
me to my question. In the dip/baths section, Bob is completely against
using Dimilin in marine systems.
<Mmm, not efficacious as a dip
ingredient>
Why is this so (especially if there are no inverts ie..
QT. I figure its just as bad as Cu++ meds, formalin...etc.)?
<...
bad? No... just that acetylcholinesterase inhibitors in low
concentration don't do any good in short exposure>
I could have sworn
I also saw a post with Bob recommending it for marine (although I can't
find it anymore). Could you explain the contradiction (that is if there
was, did his opinion change over time?).
<Not w/o ref. to where this
is stated, no>
Lastly, I assumed I had a parasitic infection as upon
dosing the QT, the clown moved erratically. Presumably because the
parasites were affected.
<... what parasites? Do you have microscopic
evidence?>
It could have been just from the clown reacting to the
meds but something (which I can't articulate...you had to see the clown)
seemed the parasites were moving to get away and burrowing in him
further.
Thanks

Re: No clowning around (like I'm sure I'm the first to come up with

I do not have microscopic evidence. It was just
an inference on an observation with out proof - merely a feeling (true,
not scientific at all).
<I see... do know this sort of guessing is
not altogether accurate. There are symptoms that "mimic" pathological
disease... with non-infectious/parasitic etiologies... Too often
"marks", abrasions, "odd" behavior are rooted in social, environmental,
nutritional, genetic... causes>
I just like to know if you would
recommend/use Dimilin in marine QT (not dip but in the QT) and under
what circumstance? If not, why?
Thanks
<I have used, and suggested
such use for arthropod zoonoses... on bony fishes (not cartilaginous).
IF one was sure of a copepod infestation let's say, Dimilin might be a
good choice. BobF>
Can Dylox 80 be used to treat velvet, brook as well as flukes, etc? No
12/31/07
Hello Mr. Fenner,
<Kathy>
I came across your
address during a search online about Dylox 80. I had a Laboutei I was
treating (hypo) for what I thought was ich. It was in a 75 gallon QT by
itself, then about 2 1/2 weeks into hypo, something was off. Feeding was
not as robust, and when she was resting, I noticed the scales sticking
out like pinecones since I was able to view from above.
I performed a
formalin bath (45 min.) followed by a freshwater formalin dip (13
minutes). Nothing came off in the bath, as soon as I dipped in
freshwater, some large, flat, transparent shapes came off. I tried to
look closely at them, they were transparent and paper thin and long
(about 1" each).
I saw one that looked like it had tan 'squiggles' in
it's body, resembling ramen noodles. Another large piece, about 1 1/2"
in length was light colored and looked like a stiff string of pearls
scaled down.
<Likely Trematodes>
I then performed a 20% water
change to bring up the salinity a little bit. I dosed De-Los from
National Fish Pharmaceuticals instead of copper, thinking copper is more
harsh. In the morning, the laboutei was labored, and she was sitting at
the bottom of the tank instead of active. I noticed a dusting of dots
all over her as well. So, would the Dylox 80 be effective with the
flukes(?) assuming that's what they are as well as velvet?
<Won't
treat either very well, definitely NOT Protozoans... w/o killing the
hosts concomitantly>
I'm wondering now if it's velvet because ich
should have fallen off by now, correct?
<... Not necessarily. IF
Amyloodinium is/was present, it could be so embedded that the Formalin
exposure did not remove it all>
Thank you very much in advance for
any advice you may offer.
Best regards,
Kathy Chu
<My comments,
input re identifying, treating these complaints is archived on WWM. I
encourage your reading there soon. I would treat simultaneously with
both a vermifuge and a protozoacide... Bob Fenner>

Hello Mr. Fenner,
Thank you for your response. I will
have a look at the articles you mentioned in your mail.
Much
appreciated and all the best in the new year.
-Kathy
<And for you
and yours, peace and prosperity. Please do read what little we have on
this acetylcholinesterase inhibitor... I have written, presented widely
on the use of this and other organophosphate use in "pond fish" and
commercial aquaculture applications... But it is a not uncommon
arthrocide in marine and freshwater "remedies"... Do look on the Net,
elsewhere with the use of other labels: DTHP, Neguvon, Masoten... Bob

How long can I use Clout?
Hi,
I am
currently treating my African Cichlids for parasites with Clout. I was
wondering how long I can/should use this medication for to eradicate the
problem but at the same time not to harm the fish.
<A maximum of two
weeks. Bob Fenner>
Thanks
Angie
