Dip Question: Dip after
QT Not necessary 11/13/2009
Hello!
<Hi Jenny.>
Hopefully all is well, and thank you in advance for answering my
question.
I've had two Clarkii Clownfish in a Quarantine Tank for 4 weeks. Both
are eating extremely heartily (fed a varied diet twice a day and turn
nothing down) and show no signs of external disease. Both are also quite
energetic.
<Good for you for quarantining.>
I'm getting ready to move them to my Display Tank and was wondering if I
should re-dip them in a freshwater and Methylene Blue. My obvious
thought is that I should, just for precautions, but I do not want to
stress out the fish to where it may hurt/kill them. Below is the
background on why I'm so worried about this.
When I initially acclimated them to the QT, I dipped them in fresh water
with Methylene Blue mixed in it. Upon putting them into the blend, one
almost immediately starting lying on his side and stopped moving. So in
turn, I moved them into the QT after about a minute of being in the
mixture. For the three days after that, they didn't eat and barely
moved, so I feared the worse as I'm sure most people would. After about
a week, however, the one that didn't lie on his side recovered
completely, while the other one picked at her food and would usually
take a bite and spit it out.
After a week, she started eating heartily, like the other fish was.
<You can dip them again if you really want to , but it is not
necessary.>
,As this will be posted in the dailies, I'm putting in a link to dips
and baths for others to read.
http://www.wetwebmedia.com/dips_baths.htm>,
Thanks again in advance (from me and my Clarkiis).
<My pleasure, and again, good for you in practicing both dips and QT!.>
Regards,
Jenny

Cleaner shrimps Death!, FW Dipping Shrimp 8/7/08 Hello. <Hi>
I have recently bought a Cleaner Shrimp from LFS and a Blue Hippo Tang
along with it, the problem is, is that as I was observing them in the
bag I realized there was a high chance the Tang recently suffered from
Ick, so I floated the bag (15min) than gave them both a freshwater dip
(8.3 ph). <Uh oh, shrimp cannot handle fresh water dips, it is quite
deadly to them.> After about 3-5 minutes I put them into the QT for
further inspection. The Tang swam around with joy, but the cleaner just
sat there (as if it were shocked). <Osmotic shock.> If my tang is
alive after the dip why should my shrimp be any different? <Because
the FW dip has the same effect on shrimp as it does the ich parasite.>
(water parameters are perfect sg 1.025, alk 4meg/L, Cal 440ppm,
mag1300ppm, ph8.3, phos amm nIte undetectable, nAte <0-0.2, tanks
running stable for 2 years) Thank you for your time, Serop.
<Be aware that FW dips are not cures of ich, the tang will need to be
treated in the QT.> <Chris>
Alternative treatment for a common marine parasite... Commercial
Crypt remedies, prevention - 07/19/08 Hello, I was wondering
if anyone on the team has had any good experience with giving a
marine fish with crypt a freshwater bath in place of a more 'solid'
technique, such as copper treatment or hyposalinity (not that hypo
is Bob's favorite)? <Some folks report success with such...
perhaps their trials involve fishes with only superficial
infestations... maybe these are principally only symptomatic...>
I'm more of a Cupramine guy myself (in a separate treatment tank),
but it seems my employer would like me to use freshwater baths
exclusively in the main display / selling tanks which also house
invertebrate life. <Mmm... I strongly suggest that they, you do
a bit of further considering here... I would do FW baths on arrival
(pH adjusted, with formalin if a commercial setting)... and even
better to best, keep all incoming fish livestock quarantined for a
few weeks before showing, offering it to the public... I would NOT
mix fish and invertebrate livestock in a wholesale or retail
setting... period> No option for separate treatment in a
different tank. So while not my favorite option it will probably
still give results and just wanted to fine tune it with some input.
If you could tell me your frequency of the bath, duration of the
bath you find effective. <Won't be... like the idea of invading
countries, murdering their citizens to "make people free", this idea
is contrary to reality. How to put this another way... it won't
work> And if you combo it with gravel vacuuming - water change,
the frequency and percentage of water changed. If you use any other
methods with it such as melafix <... API should be sued back to
the stone ages for this and other faux products and their promotion.
Really. Have stated this often and loudly enough. This product is
garbage> for bacterial infections of crypt wounds or cleaner
gobies / shrimp to lending a helping hand, or anything else which
might contribute to a recovery. <All this is gone over and over
on WWM> I was considering fw bath repeated daily for 14 days,
<... no... too much time, trouble, and stress on the fish livestock.
Ridiculous> 7 min duration, gravel vacuuming bottom of tank 5
gallons out of 60 every fourth day or so, melafix dosed daily,
<Please...> few cleaning shrimp there for luck. <Don't rely
on luck...> Considering use of a U.V. sterilizer instead of
melafix, but not likely. Trading out treatment of secondary
infections for a unknown increased destruction of the parasites free
swimming stage. experience and suggestions appreciated, and thank
you for your time, Jonathan <Thank you for sharing Jonathan. A
note to browsers through time... this is actually an indicative
case, window into the thinking, operation of the trade... A reminder
that many folks, though honest, of good intent, don't really know
much re the science of actual husbandry of ornamental aquatics. Bob
Fenner>
Re: Alternative treatment for a common marine
parasite, Crypt 07/20/2008 Again my hand is forced by my
employer's policy, ie p*tco. <Mmm, do know that I worked at
corp... as a consultant/buyer for this co. 91-94... to bring in/make
sense of aquatic livestock... Quite an ordeal> I don't agree with
the policy and have been close to walking out of door, and have been
saddened by the loss of life that could have been prevented through
dedicated quarantine / treatment systems. <I... empathize>
Either you quit / walk out or try to make the broken toy work for
spoiled child. Have had results on using melafix to clear up bad
eyes and slight bacterial damage, not as a treatment for crypt as
some people desire it to be. There was one post by someone who was
using the daily freshwater bath method from your crew, the
individual who received this suggestion responded by saying
something to the effect of "wow, everyday? That's harsh", to which
the crew replied <so is copper> <Yes> The fish has to be
returned to the same tank it came from, ie the infested tank. One
could give the fish a freshwater bath and put it into a different
tank with healthy fish, but its likely that bath won't sterilize the
animal of it and it will get the others sick. The freshwater bath /
gravel vacuum technique is used by others I have read, usually as a
hell-bent way of "I'm definitely not using a separate treatment
tank", "I don't want to treat the main display with any medication
or altering of the salinity", "I can't afford a sterilizer which may
or may not anything", and agreed the cleaner shrimp are manly pretty
placebos. <... I encourage you to make a presentation... ask for
some time to meet with the store, then Regional (Op.s) Manager... to
in turn present your input, ideas to corporate/San Diego... to
change whatever policy. Particularly "On Arrival" acclimation/baths
to largely prevent the introduction of these parasites, their
establishment in your systems> The variables I can control are
how often I give the bath and its duration. How frequent I gravel
vacuum the bottom of the tank and how much water I take out. I do
remember another member of WWM crew claiming to have effected a cure
of a flame angel by daily vacuuming of a 10 gallon bare bottom tank
50% premade saltwater. <It/this can be done... but does take
dedication, time... You seem to understand the underlying
principles> I can't do that volume with a 60, but I can do its
frequency if there is results. In this limited situation Would
freshwater bath every 3rd or 4th or 5th day with daily vacuuming be
more appropriate? <Yes> As for freshwater baths upon arrival,
I have done those, <Ah, good... with formalin and aeration I
hope/trust> and continue to do so for tangs and fish that
frequently have this problem. But even in a tank that contains only
fish delivered that week, and has had no previous problem for
months, to which all were given proper freshwater baths crypt still
does break out, so while doing proper fresh water baths on arrival
probably reduces the frequency of its occurrence its probably not
stone cold guarantee you won't get it. The last paragraph in your
reply is understandable considering the items I suggested. Its not
that I want to do them its that I'm handcuffed to poor equipment and
policy. Have risked my job and changed things and gotten good
results using a 'communal copper treatment tank' for those who
developed problems (ie crypt). And even that is not an answer to all
the various and different problems that can present itself. I just
don't have enough dedicated treatment tanks, allowances to recovery
all that can be recovered. Not that I lack the knowledge to do so.
Sorry to go on, No one on the crew has any recommendations for
this compromised procedure? Frequency/duration of bath, frequency,
percentage of gravel vacuum water change? <Five-seven minutes...
daily, all the gravel vacuumed> I think 'ridiculous' was what I
first thought about doing this as an alternative to a more proven
technique. <Just... not something I want to encourage carte
blanche (on the Net)... as a likely procedure that will be
successful for all... too much work, too stressful, too likely to
not work> cheers, hand cuffed employee <Perhaps a
move/stint in an independent shop... Bob Fenner> |
Re: Acclimation procedure 3/30/08 Hey Crew, I know that
I, as well as many other people, rely on you guys for help. You supply
us with a wealth of info and from time to time are given some thanks. I
just wanted to drop a note to say you guys are providing a great service
for us fish/reef geeks. I have read and followed many of your
recommendations, (including Bob F), and must thank you under separate
cover. A recent example that demonstrates my gratitude is Bob's
recommendation regarding acclimation procedures. I have utilized blue
meth combined with aqua nova on the acclimation of all of my new fish
additions and thankfully have had no problems since. Just wanted to
thank you guys for the education and the great service you are
providing. As always I look forward to future correspondence. Frank
<Thank you Frank... for taking the time, making the effort. Your kind
words are encouraging. BobF>
Re: sick clownfish? Now, Dips/Baths... 2/21/08 Crew,
This really isn't an area have I gathered much experience in, having my
LFS/wholesaler QT and treat for me before I collect - feeling slightly
inadequate, can I ask one of you guys with the relevant experience
field? Mike I, WWM <Okay. RMF responding> Mike, I read your
recommended links. I am a little confused. In using Methylene Blue do
you utilize fresh RODI water, (since the article does say fresh water
but later lists "new or system water")? <For dips? New, treated
water... RO/DI is fine if aerated... otherwise has no oxygen...> {I
guess you could mean net of salt}. What is the prescribed dosing, (Meth
vs. gal of RODI)? <Just "very blue"... the stock concentrations
vary... But/and Methylene Blue is very safe to use at high dosage>
"about ten mils of this solution used per approx one gallon of dip" does
this mean 10 milliliters? <Mmm, maybe... again, given commercial
concentrations vary... Just so blue you can't easily see the bottom of
the container...> The article also mentions that you could purchase
pre-made, where might one find this? <Pre-made what?> Lastly, do
you recommend dipping as part of the acclimation process. <I do...
commercially... for home hobbyists, buying local stock... quarantining
ahead... or in transit, such dips/baths are a judgment call...> In
other words when you bring a new fish home from the LFS you would dip
first in a Meth solution that is the same temp and ph of your main
display or would you first acclimate the fish by lets say the drip
method for a couple of hours. <Either first, enroute to quarantine,
and/or on the way from there to main/display tanks> This way the ph
and water temp of the shipping bag is close or equal to your display
water and then dip in the solution? <Mmm, very important to respond
to this clearly, completely: Best to measure said pH, temperature... IF
the pH is much different (esp. higher in your system than the shipping
water) OR there is any discernible free ammonia in the shipping water,
best to match the pH or have it slightly lower (this is mainly a
commercial, importer concern... or with folks moving, buying aquatic
life that is/has been bagged for hours duration... And "rinse out" the
mixed shipping/transit water, with that of the system pH over time...
Covered under "Guerilla Acclimation Techniques" on WWM> {2 step
process/acclimation followed by dipping}. Don't you feel that the fish
is stressed moving from the LFS to the shipping bag to the acclimation
procedure then to dip and QT? <Yes> Only to be moved at a later
date into the main display. Can the fish survive all of this? <Oh
yes... and you can be spared (along with other livestock) the troubles
of bringing in pests and parasites...> I understand that if we don't
take precautions then we put the entire main display tank at risk & of
course the fish if it has any disease. But I am just wondering if all
these procedures adds to the stress of the animal and in and of itself
can increase mortality rates. <Is a concern... as you well
voice/state... Hence my comment re "judgment calls"... Not all livestock
can stand, nor benefits from such dipping/bathing... IF the animals are
too weak, best to accelerate their placement (in quarantine), allow to
"harden" (rest up)... and consider such prophylactic measures on moving
further> Thanks for all the info, I look forward to your reply,
Frank <Welcome. Bob Fenner> Marine dip & bath and
chemical uses therewith, and nitrates Dear Bob, <Howdy> I
have been marine fish ( mainly angels and tangs ) hobbyist for almost a
year now. <Congrats> Having read your article dips/baths and
acclimating livestock; guerilla techniques, plus faq, confusion still
arise, thus, question need to be address to clarify. <Okay> You
mentioned fresh water dip ( 5 to 10 minutes ) most effective. Thus, one
hour bath with extra medication (malachite & erythromycin) only as an
alternative? <Mmm, this is a bit long for almost all marine species>
Since fresh water dip eventually shock the fish, no need to acclimate
the water chemistry, only temperature (warmer preferably). Is PH
necessary need to be adjusted? <Yes to pH adjustment... this is
mentioned in the articles and FAQs repeatedly... match the bag water...
elevate over time... usually simple sodium bicarbonate will do...>
You mentioned Methylene blue only act as an oxygenating agent, meaning
if I use aerator, I can skip Methylene blue? <You can... but is a
safe, worthwhile addition> However, you also mentioned Methylene blue
and fresh water eliminate itch, velvet, fungus, flukes, etc., is the
fresh water do the part? Or the Methylene blue? Or the combination?
<Mostly the freshwater... the Methylene Blue does help however. Have you
read this:
http://wetwebmedia.com/methblueart.htm> I had many reading saying
both itch and velvet cant be eliminate during the hosting and dividing
up period. Only at the time they swim up to find a new host it can
be eradicate / kill with most medication. So, is it the osmotic
shock that really kill the itch and velvet even during their hosting
period? <Yes... given these are not "too" embedded, too numerous...>
I tried fresh water dip often time (without Methylene blue) with
duration of minimum 6 minute, a lot of times I saw those parasite still
attach (already dead or still alive?) to the fish, and multiple at later
time. Is this mean some parasite survive the osmotic shock? Even fungus
remain after the fresh dip, why? <The most important factor here...
the state of health/disease of the host fishes at that time... they were
too challenged> Contaminated from else where ? <Yes! From
collection, holding... a lack of feeding, water pollution, too long in
the bags, in transit> I think I am careful enough to separate tools,
wash the quarantine tank after use, start with new water. <Yes... it
reads/sounds like you know what is going on> The one hour bath you
mentioned eight drop of Methylene blue can be added to one gallon of the
saltwater. You mentioned malachite green and erythromycin can be added
as well, but did not mention how many drop? <Please see WWM re the
issues of actual treatment concentrations... for Malachite here:
http://wetwebmedia.com/malachitegreen.htm> And with all these mix
up together I can still bath the livestock for a minimum of one hour?
<With attention to aeration, temperature control, yes> Having been
almost a year of marine hobbyist I have been able to keep most fish
alive nowadays (after so many dying fish at the early stage). There is
one thing I still unable to manage, the nitrate level remain quite high
150 level. <This is too high...> I change water every 3 week with
15% water change. <Mmm, well... you need to change much more, and
more frequently> I tried Sera bio denitrator, but has to feed
everyday. I skip using it, now trying Seachem denitrator with canister
filter running at slow flow, but has not been success so far. Can
I start feeding the nitrate bacteria with sugar? If so, how much
Should I put? <... these anaerobic digestion units rarely work... I
would look to other technologies, techniques... am sure you've read
this:
http://wetwebmedia.com/nitratesmar.htm > Or can I use Sera
Nitrafluid as it do the same purpose as sugar? But I read Sera
instruction not to pour Nitrafluid direct into the tank. <I would not
put either directly into the tank... these need to be drip-fed into the
anaerobic chamber (the canister filter) to be of use... you can
experiment here... but I would go with a refugium, DSB, more live
rock....> Appreciate your attention, Regards, Sumadi <Keep
studying my friend. Bob Fenner> Naso et al. not for reef
tanks? Merits of dips/baths 6/31/05 Matt from Critter Cabana in
Newberg here, We have a customer who was told by another local fish
store that his Naso tang and a couple other fish needed to be pulled out
of his reef tank because water parameters were very unstable in a reef
tank due to the necessary chemical and mineral supplements in a reef
system. <Huh?> This seemed odd to me, but it came from the
person who most people in the Portland area consider the local authority
on fish health issues, just curious if you knew where he was coming from
on this. <Wacky in my book/s> Another strange
recommendation, I know that most if not all of the wet web crew
highly recommends dips as preventative disease control and acclimation
into the quarantine system, and it has been the only success we have had
with ich control here at the store. Anyway, we won't offer guarantees
for customers unless they use our recommended Fw dip acclimation. Well,
the other local stores in the area have caught wind of this policy and
are telling our customers basically that we are nuts and that no
respectable marine aquarist would ever perform such an activity.
<Mmm, I disagree... dips/baths were S.O.P. in our retail stores... are
so at the best wholesalers on the planet (Quality Marine in Los Angeles,
Tropical Marine Centre in the UK), collectors...> Are your
thoughts pretty strong on this issue as in its hands down the best way
to acclimate? Is the dip some sort of rogue method? Or is it a
professional standard? <Is posted on WWM... hobbyist to
commercial> I'm hoping to share this email with customers to provide
a simple authoritative answer on some long standing arguments.
Matt <Glad to share my opinions, experiences... first and other
hand. Bob Fenner> Quarantine and Dipping of Acropora 7/14/05
Hi, I have read recommendations to dip all new Acroporas in ReefDip,
FlatwormExit and Lugol's (I presume separately?). <...> We
have several frags in quarantine for 4 weeks prior to entry into the
tank (for ich as well as other parasites). During that time, I have
examined them every few days with a magnifying glass and don't see any
bugs at all (and the color looks very good). A few of the frags have
harmless commensal crabs (smooth shells). I hate to hurt the crabs by
doing a dip and don't want to add unnecessary stress to the corals. If
examined regularly for 4 weeks and nothing looks out of the ordinary,
are the dips still necessary or could the corals be pronounced "bug
free?" Thanks in advance! - Doug <I
would not use any of these or other "dips" with quarantined corals
unless I observed trouble that warranted such. Bob Fenner> Re:
Quarantine and Dipping of Acropora 7/14/05 That is what I
thought. I just wanted to make sure that Redbugs, etc. didn't have some
sort of long cycle where they might lay in wait more than the 4 weeks.
<Nah! You'd see them by then> Thank You! <Welcome. Bob Fenner,
soon to have a contract on him for debunking chemical products in the
trade/hobby> Bobbing for ich... important, interesting methods
for avoiding, treating external parasitic (mostly) complaints of marine
fishes - 01/12/2006 Hello, <Hi there> Could you
help clear something up. Will a freshwater bath on a marine fish
destroy some of the encysted parasites of ich or velvet? <Often so,
yes... this is posted... on WWM...> I get conflicting information
on this. At the store I work at, we do keep copper in the water for
parasite control in our marine section. <Very common practice in the
trade> So when the parasite drops off and the swarmers bust out they
will shrivel up and die. <That is the hope> But if I could give
the fish some relief from the load of parasites it currently has on it,
I would like to do that. <You are wise here... my urgings for
prophylactic dips in the industry... from collectors forward, have been
emphatic and constant going on three decades... Please see WWM re
"Guerilla Acclimation"...> Giving the fish a pH adjusted temperature
adjusted freshwater bath when it obviously has something, that sounds
like good advice. <We are confluent in this opinion> We know a
freshwater bath will kill or reduce a lot of other pathogens that could
be hitching a ride on the fish, from flukes to Brooklynellosis. But
besides killing all the other stuff that might be in the gills on a fish
that's showing spots, Will it actually help to reduce the load of marine
ich or velvet? <Oh yes. Done correctly, they are virtually
eliminated, excluded with such practice> Or am I only giving a bath
to kill whatever else might be on the animal and waiting until the
encysted parasites drop off? <If your systems are "specific pathogen
free", you will not have such pathogens to reinfect/fest them...> | I
had the idea that the freshwater bath might take off some of the fishes
slime coat and expose the parasite to the killing freshwater. Or is
that not the case? <Yes... with most fish species, in good initial
health, such exposure results in more slime production temporarily>
In a related idea of giving a saltwater bath to a fresh water fish.
Sometimes I will see a fish arrive covered so heavily with ich
(freshwater) that I go 'man, that's horrible'. I don't think the animal
will survive to where those encysted parasites drop off to be killed by
the medication that's in the water. So how about a salt bath. <Can
be utilized with good result with many types/groups of fishes... not
all. One must be attentive (there while doing this, closely observing),
using aeration... removing the fishes if/when show too much stress>
I've read a few authors suggesting a 1% or 3% bath, in that it would
take off the fishes slime coat exposing the parasites from their
slime coat fortress to be immediately destroyed, and it encourages the
fish regenerate a new slime coat more aggressively. <Yes, ideally>
The bulk of the question affects how I handle a fish that I see is
'covered' Can I do something now to help it get some of those nasties
off it and medicate. Or are my hands tied and I medicate, wait, and
hope it survives until they fall off. <Can do much... the best, most
logical place is in transition, during handling, placement on arrival...
during acclimation... next, by way of quarantine procedures... Of
consequence, careful species and individual selection/sources, and
appropriate, stable environmental, nutritional inputs> In a
semi-related note I was browsing through the posts on marine velvet and
a reply from a person Anthony from a post called "Oodinium". He
mentioned a preference of formalin over copper, in that copper would not
penetrate deeply into the flesh to kill the parasite. I thought that
even the powerful formalin would still run into that same problem. The
parasite is protected by its slime coat fortress, that no medication
could penetrate into it. <Mmm, well... metal and formalin containing
material does produce such irritation that much of the slime coat of
fish hosts is sloughed off, with not-too-deeply embedded parasite fauna
going with it...> You just wait until it falls off divides and
kills the free swimming state. <Mmm, better to remove the stages
from the host, kill them in the process if possible, and poison them in
off-host stages as well. Bob Fenner> Thank you for time,
Jonathan Fresh Water Dips 9/13/06 Bob and
Staff - <Hi> I'd first like to thank you for such an informative
site. <Thanks for using it.> I recently ran into a problem with
ick and according to your web site you advise dipping new fish in fresh
water before putting them in quarantine. I get my fish from a
wholesaler who keeps their salinity at 1.010 (yes I know that is low) -
I keep mine at 1.020. <Low too> When should I give them the freshwater
dip; after I acclimate them to my water settings or should I dip them
first? <The FW dip should match you tank water in everything except
salinity. Ph, and temperature should match, so acclimating to the tank
is acclimating it to the FW dip.> Or is it too much stress on them to
dip at all? Thanks for your help. Jim H. <For
ich I do not fresh water dip, not really that effective in my
opinion. Better off just going with copper or hyposalinity
treatment. The dip is quite effective for some other illnesses, in
these cases dip before QT.> <Chris> Dips Hi Bob. Will
fresh water dipping actually kills off all external and internal
parasites? Secondly, will the daily of fresh water dipping causes stress
to the fish?( I mean for those fishes with parasites) >> Many
external types weakened to destroyed by such procedures. No internal...
any manipulation is stressful... the question is whether the "trade-off"
is "worth it"... as time goes by the universe appears less didactic.
Bob Fenner Dipping, acclimation, quarantine for new fish
Good morning: <Good morrow to you> I'm going to be receiving a
shipment of stock today from one of the national suppliers. The stock
will have been in a FedEx container since yesterday. In reviewing the CM
Aquarist I noted that you recommend that fish who have been traveling
for a bit should go directly to their quarantine home. Is this in lieu
of freshwater dip first as the dip is too much additional stress after a
bunch of travel time? <Good question. A subjective evaluation on your
part necessary here. If the livestock is apparently beat, simpler
acclimation and to quarantine> No invertebrates are coming or in the
q-tank so the stock can be medicated there. <Are you familiar with
our website? Please read here:
http://www.wetwebmedia.com/quaranti.htm and the related FAQs
(linked, in blue, above)> Your thoughts as always appreciated.
Charles Shatzkin PS: this dealer actually encourages use of a q-tank!
<Outstanding. Thank you for writing. Bob Fenner> I've been
reading your column daily over the past few months, and I'd like to
tell you how much I enjoy it. I'm new to the marine fish hobby, though
I have a lot of experience with freshwater setups, and I've gleaned
quite a bit of useful stuff from your Q&A's. My question is about the
fresh water dip that some folks recommend for new additions to a marine
tank. From reading your column, I understand that you advocate this
practice, but the guys at my local fish store seem to frown upon it.
They claim that it unnecessarily stresses the fish, and can actually
kill them. Can you tell me what risks are involved in fresh
water dipping? I've just gotten my 150 gallon fish-only tank cycled, and
have added some fish who's health I'd really like to protect. On a
related note, if I'm going to be doing fresh water dips, would it be a
really bad idea to do it in one of my tropical fish tanks (complete with
tropical fish)? One more thing: I have the following setup: 150 gal
tank, over flow filtration with one return. Wet/dry system which uses a
commercial sized bio-wheel for biological filtration, a Lifeguard
AF-94-19 mechanical filter, Lifeguard AF-93-19 chemical filter,
Lifeguard QL-40 UV sterilizer, and a Top Fathom TF 110A protein skimmer.
Can you think of anything else I should add to this setup to provide for
a cleaner and healthier tank? Thanks for your help! Dan >>
There are few risks or real added stress (compared with being caught,
hauled out of the ocean, thrashed about being brought to a facility,
kept w/o food, heavily medicated, being housed with species that you
don't associate with in tiny cubicles, boxed and air freighted in
absolute darkness and then pretty much the last few items through
wholesalers then retail... Give me a break, the freshwater dip is a
breeze by comparison. And, this is the best way of knocking off external
parasites like Ich and velvet... I've just come back (well, not quite,
now I'm in Hawaii) from helping friends develop receiving protocols for
wild imported (from the Solomon's, Tonga, Fiji, Vanuatu) fishes... all
of which we run through freshwater dips. Anyhow, there are few risks.
And my expanded, though less emphatic views on the topic and means can
be found in articles on my wetwebmedia.com website, including
references. No, don't do the dips in a freshwater tank. As you will
find, it's best to make the dip water from new tap (Dechlor/am/inated)
and buffered (we just use baking soda, sodium bicarbonate)... with or
w/o other additives. Re your system, do keep your eye on that sterilizer
(real problems with these over the years)... and do investigate what you
might do to modify that wet-dry... to a Berlin system at the least, to a
continuously lit Caulerpa and mud filter at best... Many roads, same
destination: clean consistent water quality. Bob Fenner
Re:
freshwater dip - I have been quarantining new arrivals for 2 to 3
weeks before introducing them into my main tank, but I have not, to
date, been applying a freshwater dip - largely out of concern of process
I generally take great care in following in transitioning the fish from
the store's water to my quarantine tanks? Do you skip the acclimation
process entirely - or acclimate to quarantine water, then dip, then
introduce to the quarantine? Also, I do not (have not had to date)
medicate my quarantine tank, I just use it as a place for the new
arrivals to get acclimated and regroup. Do you recommend adding copper
based medication to the quarantine as a protective measure.
Similarly, what is your preferred approach to the freshwater dip - just
fresh water (Ph adjusted and dechlorinated) or water treated with
Formalin or another copper based medicine. Many thanks in advance for
your insights. >> The stress of freshwater exposure is minimal...
with most fish species, negligible. I dip/bath the new fish livestock on
the way into quarantine. And good for you re the lack of using "poisons"
(cause that's what they are) in your quarantine or dip/bath protocols...
if the livestock is healthy to start with... using copper, formalin et
al. is unnecessary... commercially (like in collecting and wholesale
situations) I do utilize such expedients... personally, no. Bob
Fenner In his book, Bob Fenner recommends that wrasses be
quarantined "quickly." Mine arrived a week ago from FFExpress,
and he's doing fine in the quarantine tank. Should I move him to the
display tank or wait the standard two weeks? Just wondering. >> If
the animal(s) seem to be external disease free, and perhaps growing
skinnier from the quarantine procedure, I might well go ahead and run
them through a buffered freshwater dip on their way, and just place them
in the main tank. Besides many of the wrasses (family Labridae),
other groups of fishes that often benefit from a "fast tracking" through
quarantine are gobies, blennies, dragonets/scooters/mandarins...
basically any organism that might starve, or suffer more psychological
damage from the process than the risk of parasitic infestation warrants,
I would dip, keep in quarantine for a minimum of days (to let it rest,
assure it won't "just" die) and move it on, with another dip on the way.
Bob Fenner Baths. Which is better, a full quarantine or
a freshwater bath? >> >> Quarantine in general, but BOTH are BEST.
Bob Fenner Dear Mr. Fenner, Thanks for the reply! What chemical
dip mixture and what duration would be safe to use on macro algae? Would
a freshwater-Methylene blue mix be okay? Regards, Alec >> I
would just use a pH adjusted (baking soda to 7.8 would be fine)
freshwater (chloramine removed) mix. Bob Fenner Ich/FW dips
Bob Do you recommend a freshwater dip for a new arriving fish before
putting him in quarantine, or waiting a couple of days? <Not all fish
species, specimens routinely... some arrive too weak to dip, others are
historically worse off for the operation, unless they are judged
parasitized...> I am talking about an overnight delivery instead of a
fish from LFS. How long of dip is best? I am watching fish closely. If 5
minutes is effective on killing parasites I obviously don't want to
leave fish in dip for ten minutes. I understand that some fish will
react differently. But I guess I am asking what is optimal. <Please
read my dip/bath articles starting here:
http://www.wetwebmedia.com/dips_baths.htm and the FAQs files beyond>
By the way, my current butterflies seem to be fighting off parasites. I
believe you can judge a lot about a fish by closely watching him eat.
<Yes! This is so> If there is any change, something is probably up.
These fish would peck at my finger if I let them. Saw two of three
pecking at algae. Time will tell. What is best, in your opinion,
vitamin, for supplement with my concerns? <A liquid complex...>
What do you think about garlic? and garlic and vitamin supplements on
the market? <Both, all of these have their place... my opinions,
related background information are posted on the WWM site... there is a
search feature there if you don't want to avail yourself of the Marine
Index/Site Map> Fish don't seem to crazy about it, but if it is
important they can be trained to eat it. D Stanley <Not altogether
unlike human food preferences, eh? Bob Fenner> Freshwater dip
Dear Bob, <Steven Pro at your service tonight.> Thanks for your
previous replies, always a great help! Can one give inverts, in
particular hermit crabs, snails, soft & hard corals, freshwater
bath/dip? <No to all above except some corals.> If so, for how
long? <Again, only for some corals and generally less than one
minute.> Will this eliminate any parasites like Oodinium? <Inverts
have their own set of parasites. Their is little risk of infecting fish
with a coral. The real risk, more than likely, is in the water from the
store.> Thanks again, Patrik Fredrikson, London <You are welcome.
-Steven Pro> Is a dip still worth it if I have a UV Sterilizer?
<Yes, a properly conducted freshwater dip is a highly effective means at
parasite treatment. UV's are notorious for not being maintained and
installed properly; too small of a unit, too fast of a flow rate through
it, water not prefiltered sufficiently, lamps not replaced often enough,
quartz sleeve not cleaned routinely, etc. Even better than both is a
quarantine tank, though. -Steven Pro> Re: ich Hi again
as I was fresh water dipping my Sweetlips I decided to inspect him it
looks like the ick is gone except for one part on his fin he has these
little tiny sacks look a little like blisters but they were hard I was
unable to scrape it off is that another stage of ick or something else.
<not another stage... be prepared with broad spectrum antibiotics to
prevent secondary infection> Should I keep up with the same treatment
the powder blue is showing no signs off ick or anything. <my
apologies... so many e-mails, not sure where the powder blue is at this
point. If in QT and the water is medicated, then I would say it would be
fine to pause on the FW dips for him as long as you see stabilization or
improvement. Continue to do water changes from the bottom of the bare
bottom QT to control parasite cysts. Anthony> Too late for a FW
dip? Hi there, <Hello> I recently sent an email about a
Rusty Dwarf angel that wouldn't eat. I took him back to the LFS until my
ammonia level came down (which I think shot up because I added LR and LS
on the same day I added the Rusty). I did pick up a CPR BakPak II
skimmer at the same time. (according to this site - a must have!). He
wasn't eating and I was afraid of ammonia poisoning since my level shot
up to 1.0. Did water changes everyday. Well, I got him back when
everything was normal. The LFS said that he was eating live brine. I
picked that up too but I have yet to see him eat. His swimming is normal
and he comes out a lot to look at me (very friendly little guy). But I
notice that his mouth is swollen, as if he can't close it. This is what
I am suspecting is the reason he is not eating (perhaps it would hurt
him). <Good observations> Anyway, I do not have a QT as this is
my first attempt. I have a 20 gallon tank. <Small for this species>
I have been reading about FW dips and was wondering if this could help
him. I have a cleaner shrimp that he does go to, but the cleaner shrimp
always seems interested in checking his gills. Anytime the cleaner
shrimp goes to his mouth, he jumps away. This is my first fish, and as I
said, such a friendly little guy. Can I do a FW dip at this point - will
it help? <Not in my opinion. I would leave this specimen to the care
of the Cleaner Shrimp, self-cure. Do keep offering a mix of foods...
perhaps with vitamin, HUFA supplementation/soaking> If the answer is
yes, please clarify one thing for me - is FW actual freshwater or
diluted saltwater? <No... Please read:
http://www.wetwebmedia.com/dips_baths.htm and the FAQs, linked files
beyond> Also, what are the steps ( I'm looking for a 1. 2. 3. which I
really can't seem to find on this site). <There are such approaches
detailed here and there... on the area cited> Again, thanks for all
the help. And I promise that as soon as I know what I'm doing, a QT will
definitely be part of my program. <Real good> My deep gratitude.
Debra <You are welcome my friend. Thank you for sharing. Bob Fenner>
Annularis in Quarantine Hey Bob. I have been using the site now
for a while and it's great. I've been recently searching the FAQ's for
my angel but had no luck. I have an Annularis Angel in QT treating with
formalin and malachite green for about two weeks now. My nitrites are
about .25 and sometimes .50. My angel was doing VERY WELL and all of the
sudden appeared these really small white spots all over his body, I mean
he's covered in them. There are millions of them sprinkled on his body.
This has happened before and then just gone away with the medicine so I
thought it was ich or something. <Me too> But, they really don't
look like ich or velvet, I've never seen this before. He broke out in
these and rapid breathing in less than a 24 hour period. Could this be
the formalin or mal green doing this to him? <Yes> Or is this
some kind of disease? <Not likely... all external parasites should
be gone with the first exposure to the formalin... Am given to suggest
that you do a pH adjusted freshwater dip and move this fish into the
main/display tank... this is what I would do> I need to find out how
to treat it and what this is from. This angel went from eating like a
pig yesterday and swimming all over the tank and this morning I wake up
and he's covered and floating in the middle of the tank not really
swimming much. If someone could respond quick because he's on his way
out, I'm running out of time........THANK YOU!!! Jesse <Got to
ask: Do you have a microscope, some simple gear for doing a skin
smear... look/see? This is also what I would do... look into a cheapy
QX3... this is what I have... it works fine... I would move this fish.
Bob Fenner> Formalin, Malachite, Annularis Follow-up Bob,
YOU'RE A LIFESAVER!!! I actually already started to acclimate him to my
display tank because that was my first intuition. My gut feeling was
that it was the water and/or meds bothering him. Glad that worked out
well, lol. I thought that it takes a while for any medicine to kill
parasites... <Mmm, depends on what types... Formalin kills most all
on contact... all external> ...and that was the reason for a minimum
2 week to a month QT period (to make sure no new cysts hatch and more
parasites break out)? <If the live stages were present on the fish...
they'd be killed... if the fish was new, where would the encysted, other
life stages come from?> Would the formalin and mal green kill
Oodinium and Brooklynellosis and could it be a possibility that he has
either of those? <Would kill them, unlikely it's Brooklynellosis,
possibly Amyloodinium, but not at this stage...> I'm only asking
because at the end of the email you mentioned a microscope. Are you
concerned that there really could be a possibility that this could be a
parasite (ich/velvet) and not the medicines? <Am always concerned...
the only way I handle toxic chemicals, expose them to livestock is to be
sure of their efficacy. Bob Fenner> |
