Queen Angels
I am very interested in obtaining a Queen Angel for my 90 gal fish only aquarium that has been running 4 1/2 months. I use a trickle filter set up with bio wheel and 10 gal sump, a Pro. skimmer and a More Zone 30 Ozonizer. I 
have 1 Flame Angel 3 inches, Three Spot Angel 4 inches, and 2 Golden Head Sleepers 2 1/2 inches approx., 2 cleaner shrimp & 30-40 lbs of live rock. 
First of all, would I be overloading my tank by adding a 3-4 inch Queen Angel 
(I'm thinking long term)? 
<I think the Queen would be a poor choice, not so much from a crowding standpoint, but behaviorally... with the other two angels... The Queen would get big... much bigger than the others in months... and bully them relentlessly>
Secondly, I have noticed in 3 different local shops in Torrance, Ca that all of the Queen Angels that have been coming in 
have been coming down with what looks like lymphocytes. The fish are all well colored, active and alert. Is this a trend with imported Queens that is currently common?
<Yes, I think so too>
One of the store owners, who I deem very reputable, says that he has noticed a decline in the quality of the Queens over the last year. In fact, he says that he is having more luck with Emperor Angels. Is this true and am I rushing things by looking to add this fish? Any help would be greatly appreciated.

<You're not rushing yet... I would look for other non-angel livestock for your 90,

Queen angel update/HLLE cure/Caulerpa Culture
dear bob,
back in November I e-mailed you about the HLLE problem I was having with my queen angel. you were kind enough to respond right away with some suggestions that I add a macro algae culture and freshen the live rock.
<yes, I recall>
well since that post I wanted to let you know that my angel has improved dramatically! the lesions that once ravaged here face, eyes, and lateral line are now limited to her "cheek" area. it seems that she has a ravenous taste for the Caulerpa and I provide it to her 3 times a week. thank you so much for your suggestions.
<Ah, great to hear of your success>
the fresh algae is costing me close to $10.00 a week in addition to all the other frozen goodies, fish eat better than I do! As such I've tried numerous ways to grow it myself but with no luck. several times I tried placing a fresh harvest in a floating acrylic breeder in the display tank but the algae deteriorated in 4 days. my 75 gallon tank is lit with 2 Coralife 10,000k fluor. and 2 actinic lights.
I have also tried cultivating the algae in my 100 g reef system equipped with power compact lighting. however, a $25.00 "bush" attached to a piece of live rock turned my tank green and then died in as many days. now as a
last ditch effort I have placed some freshly harvested cup, blade, and grape specimens in a 20 g undergravel filter set up. 12 hour light with Coralife reef sun and a generic incandescent plant bulb. there are 3 small
fish in the tank to fertilize - so far it seems that the algae is also dying in this tank too. what could be wrong?
<A few things... I would go back to/with the compact fluorescent lighting, use just some live rock for attachment, and boost both alkalinity and biomineral content (mainly calcium)... keep these above 4 meq/l and 400ppm respectively>
I am seriously considering installing an ecosystem refugium from Leng Sy's website however if I'm unable to grow the algae what is the point? your thoughts?
Gisela
<The miracle mud systems are also very good/worthwhile. Bob Fenner, who would also look around, ask your local marine hobby club, perhaps the stores if they know someone who has the opposite problem... that is, too much Caulerpa... not uncommon.>

Sick Queen Angel
Bob,
I'm about to lose a really beautiful young Queen Angel (my 3 year daughter calls her "Nicca") to some kind of parasite. Her eyes are clouding over and she has been scratching herself in the tank. I went and bought your book
(Extraordinary, by the way.), but I am new to this responsibility and have only one 55 gal tank and no quarantine set up. I tried freshwater dipping for 10 minutes as recommended by the shop I frequent and parasites leap off except for the eyes and now one fin seems in trouble. She only gotten more lethargic.
<How long have you had this fish?... What other livestock is in with it (good clues here) that is doing well, okay?>
what do you recommend I do?
<Please QUICKLY read over the parts of our website: www.WetWebMedia.com on "Marine Parasitic Disease" , the FAQs and treatment sections... I would lower the spg and even move this specimen if you have the facility to do so... Act now!>
I appreciate your ear.

<Be chatting... pls send all corr. to By Bob Fenner. Bob Fenner>

Re: Sick Queen Angel
Bob, 
Thanks so much for your response. I've had this fish for a little less than 3 weeks. Other specimens in the tank from oldest to youngest are one med coral angel, one purple tang (red sea), one bicolor angel, one medium copperband, one small maroon clown, and the small queen we are treating. 
However. I noticed last night that the copperband is started to scratch on the rock. I have a good bit of live rock in the tank as well. The coral, tang, clown, and bicolor all seem to be doing well. 
I've read over the article as you suggested and assume that I'm dealing with Amyloodinium ocellatum, though why are the eyes clouding over. Because I'm limited to my one tank, I think I have to try a copper dip ( I think you call 
it Methylene blue in your book). 
<Sounds like Velvet, yes... and a real need to move quickly, treat with environmental manipulation, vitamin prep. and cleaners... ahead/in place of copper (which will kill much of your live rock... while it is absorbing the copper...)>
The Queen Angel is doing better today, has gotten more active, and is eating some. She still has the parasite in her eye, but I'm encouraged. 
Again, thanks 
Michael

A 6 year old queen angel .
Hi Mr. Fenner
<Hello>
my name is Andrew Davies I live in s Wales U.K. . a fellow marine fish keeper , asked me to e-mail you concerning his queen angel , his system is run on a wet dry trickle tower system +a 300 gallon fluidized bed the system has been up and running for about 6yrs in all that time . the queen angel has been with him he, purchased the queen when she was small has moved her twice ,when he was upgrading his system and the queen has been very well indeed but for some unknown reason last week he did a 20gallon water change as he has always done , but for some unknown reason , she has stopped feeding , and is not as active as she normally after many hours of watching her not feeding , we where wondering if you could enlighten us  to our problem, would be very grateful to hear your views on this matter.
I look forward to your reply .
yours faithfully MR. ANDREW DAVIES + MR. ANTHONY GEORGE
<A good record here of husbandry... could be that "something" was out of the ordinary with the source water that day (this happens quite often in the States... for instance, the municipality "pulses" chloramine (sanitizer) at several times a regular concentration at times). I would not panic at this juncture, but do try supplementing the food and water with an aqueous vitamin/HUFA product and be patient. Do also please read over the following: http://www.wetwebmedia.com/water4maruse.htm
particularly developing a routine of pre-mixing and storing new seawater ahead of use. 
Cheers, Bob Fenner>

6year old queen angel
to who it may concern,
I have a 150 gal marine fish only system which has been running for about 6 yrs. up until about a week everything was fine but after carrying out a 20 gal. water change which I do every 3 weeks my 6 yr old queen angel has stopped feeding and become lethargic. her breathing has also slightly increased. I use r/o water by the way. I haven't added any fish for a long time and all my fish get on well. all the
parameters of the new water were identical to the tank. I filter the system with a trickle filter/ sump tank, fluidized bed, U.V and heavy protein skimming. am I doing too many water changes even though the experts say to do so? 
<Ah, a bit more, different information. Your reverse osmosis device should be taking care of problems with your source water... do check the carbon contactor (perhaps with a chlorine test kit and a sample of the produced water) to see if it has become exhausted... and renew (British for "replace" for U.S. readers)>
what could possibly have disrupted the fish or the balance of the filter system?
I don't think its just a coincidence. thank you, George
<Something definitely did... I would still pre-make, aerate newly made water. The volume, percentage changed out is fine. Bob Fenner>

Re: a 6 year old queen angel .
hi Robert
Andrew here with reference to your e-mail Anthony and myself share the same r/o unit and I have not had any problems with my tank, there are a couple of large fish in the tank , with the queen do you think she needs more space .
<Yes... likely something in the range of about twice (let's say 300 gallons) of what you have this fish in now. Bob Fenner>
thank you for your reply a Davies

Re: a 6 year old queen angel .
hi Robert Andrew here again
the queen is not in 300 gallons she is in 150 gallons 
<Yes, I understood that from your previous e-mails, pls re-read my last>
I have the 300 gallons in my system and I have a large grey angel in my tank with a half-moon angel , .Robert can you tell me which off the angels is the most difficult to keep +why also can you tell me what are the chances of ME, keeping Moorish idols in my tank please ..
<Please review the articles on pomacanthids and the many FAQs files associated with them on our root web: starting here: http://www.wetwebmedia.com/marine/fishes/angels/index.htm>
thanks for you advice on the r/o unit we shall be changing the 3filters in the unit ASAP.
<Real good. Be chatting, Bob Fenner>
thanks again Robert Andrew

Re: Queen Angelfish
Anthony,
Here is what I have been able to discern from the time that I wrote you
yesterday. The problem with the Queen Angel wasn't one of tank mates,
apparently. Rather I think it may be a question of water movement in the tank. 
<interesting>
I noticed that the angel likes to scrutinize everything that it eats.
With my original setup on the tank, 2 aqua clear 300's and 2 power heads
moving water around, it had a difficult time chasing food around, watching it closely and then eating it. The food appeared to be moving a little too quickly for the fish to perform all of the aforementioned actions, and eat a decent portion of it. 
<very dubious, my friend... water flow on the reefs where these fish are collected make our tanks look like quiet tide pools. Still... I trust your observation and perhaps it is somehow related>
My solution, thus far, has been to turn off the 2 power heads and let the food float for a little while in the tank. So far
he hasn't had a problem getting it. I have fed him twice using this
arrangement, and once more with all of the filters and power heads running. Sure enough, with all of the water moving around he had a difficult time feeding.
<fair enough... if this will go on for long... consider a little relay/timer to automatically turn pumps back on>
Your comments about the Tuskfish were cause for some alarm, however. As I said the Tuskfish hasn't been aggressive towards the Angel. Nor does it seem to be an overly frisky eater, as you put it. 
Nor does the Angel seem to have a problem being out and eating at the same time the Tuskfish does.
<not at all a realistic evaluation without watching fishes mature (sexually especially) in the 1-3 year picture and beyond. many such Angels eat parasites (as cleaner fish) as juveniles, mucho algae as subadult and anything they darn well please as grumpy adults <. Yet a 2 week or even six month snapshot of such a fish or fishes is not even remotely indicative of how it/they will behave as it/they mature...no matter how much we both may wish for it <G>>
I was told by multiple people that Tuskfish weren't aggressive, or overly territorial fish. 
<I would indeed agree... mostly a problem with great activity and assertiveness. Can be very intimidating to other tankmates who although don't get molested by the Tusk, are still out competed and end up being stressed significantly over tie for it.>
The person I purchased it from quipped that it looked the part of a real brute, but in fact was quite gentle toward other fish. 
<hardly an unbiased opinion. I, instead, am not trying to sell you anything... just sharing opinions...heehee. But seriously... I do agree that for its size, it is especially passive... unless you are a crustacean <wink>>
This was the reason I bought the fish in the first place...well okay he also looks great. Is this not true? According to your email, I should have grave concerns for any other fish that I put in the tank with him,
particularly as he gets older. 
<again... not attacking but out competing. Still can lead to attrition and intimidation into poor health for some fishes>
If this is the case I may move him to another tank.
<as long as the angel doesn't hard him and the tank is large enough... it sounds like it may very well be fine. Quite a beautiful pair too>
Please understand, also, that I am well aware of the special requirements of each fish. I currently have (2) eighty gallon tanks right now, and I'm in the process of making (2) two hundred gallon tanks in my basement. 
<very well... but the two fish as adults are still a lot of fish for a two hundred gallon tank. Two foot worth of dog confined to a six foot cage doesn't sound like much fun... and I like fish as much or more than dogs...heehee>
Outside of building the tanks, which is a much larger project than I had first anticipated not to mention very expensive!!!!, it has also proven necessary to pour a more stable reinforced concrete pad in that section of the cellar. The plan is to have this finished by the time the fish are too big for their present homes.
<excellent... best of luck in this endeavor>
As always I await your response with baited anticipation.....
BTW, you may remember the little Blonde Naso that I wrote to you about a few weeks ago. 
You will be pleased to know that he is doing very well. Again a very large thank you on all of your help, and advice.
<always great to hear follow up success stories... another big beautiful fish... hmmm, have you thought about skipping the two hundred gallon tank and just building a saltwater lagoon in the basement? How cool would that be!?!>
God speed, Michael
<kindly, Anthony>

Please Help Me, My Queen Angel is Sick!
Dear Mr. Fenner,
<Steven Pro in this morning.>
About one month ago I purchased a Queen Angelfish from a local aquarium store. It is a gorgeous specimen and little over 4" in length. My tank setup is approximately 10 months old and is 46 gallon bow front
<Very cramped quarters for this fish. It will easily reach 12" and up to 18" in the long run. Needs a tank at least 180 gallon (2'x2'x6') for proper growth.>
with 55 lbs. of Fiji live rock, and a crushed coral substrate. I have a Tetra Tec PF300 power filter on back and a SeaClone Protein Skimmer also mounted on the back. The other inhabitants are a Humu Humu triggerfish and a small Fiji Devil Damsel. I do not currently have anything else like shrimps or invertebrates. My Queen has developed some kind of infection whether it is parasitic, bacterial, or fungal I can not determine, all I can do is describe it. It looks exactly like little tiny white pieces of feta cheese growing on its caudal, anal, dorsal, and pectoral fins. The majority of the "junk" is concentrated to the caudal fin where the material began to appear.
<Sounds like a good description of Lymphocystis, a viral infection. You can see a picture of it here http://www.wetwebmedia.com/viraldislymph.htm on another Queen Angelfish. If you follow on to the linked FAQ files, you will find more information on causes and treatment.>
The fish also seems to have Ick and/or velvet with small salt granular type bumps on its fins and body.
<Could be Marine Ich/Cryptocaryon or small patches of Lymphocystis. More info on Ich can be found here http://www.wetwebmedia.com/parasitf.htm>
In addition to the other aliments it also seems to be developing a case of Popeye in it's left eye.
<Wow, this fish is getting hammered. I am guessing some aspect of its environment is off. Popeye info here http://www.wetwebmedia.com/popeyefaqs.htm>
I have observed it swimming with its mouth open and its gills pumping quite rapidly. The fish also has erratic swimming patterns that include darting, rapid swimming, and tremors or rapid shaking. I have checked all my levels and my pH is at 8.1, and the others NH3, nitrite, and nitrates are at 0. Specific gravity checked out at 1.023. My Humu Humu Trigger seems to have marine ick but is showing no other signs of the aliments that the Queen is facing. I feed my fish twice a day with a broad diet containing a variety of frozen foods, seaweed selects
algae strips, live brine shrimp, and occasionally shrimp from the Giant. I am currently trying to treat my fish with a combination of Maracyn-One and Organi-Cure copper sulfate treatments.
<Ugh, in the main tank? A terrible idea. Your liverock is now dead rock and forever contaminated. Same goes for the crushed coral. All meds should be applied in a separate quarantine/hospital tank.>
I have removed the carbon from my filter and turned off my protein skimmer. After one and a half weeks of copper-sulfate and 5 days of Maracyn I can see no improvement in the condition of my Queen in fact it seems to be getting worse.
<Neither would help the Lymphocystis. Could in fact make it worse.>
I tried doing a freshwater dip but it nearly killed the Queen after getting its gill barb stuck in my soft net, and from the shock of the freshwater. Please Mr. Fenner, I am desperate and have the means to fund a strong fight for the fish but I need to know if what I'm doing is right and if you have any suggestions, any at all, to please give them to me as soon as possible. I appreciate you reading my plea and taking the time to help. Thank you for your consideration. -Dan Heffelfinger
P.S. I have read the Conscientious Marine Aquarist cover to cover a few times and enjoy it very much.
<Do read through the above links to enlighten yourself as to the causes and corrective measures. Good luck. -Steven Pro>

Queen Angel Problem
Hi Bob,
<Steven Pro in this morning.>
I came across your website today for the first time trying to figure out a complication with my Queen Angel. The problem is for the last week it's only breathing from one gill at an accelerated pace.
<Sounds parasitic; Cryptocaryon, Amyloodinium, or Gill Flukes are all possibilities.>
Behavioral patterns are normal, water conditions are fine, and the rest of the inhabitants are healthy. I've tried to locate this problem on other websites the past few days and came up with no results. Is there anything I can do to help this great fish. I really don't want to lose him.
<Look up those diseases on our site, www.WetWebMedia.com, for treatment options. Quarantining and freshwater dips or formalin baths would be my course of action.>
Thanks, Brian
<You are welcome. -Steven Pro>

Sick Queen Angel?
Hello how are you today ?
<Fine, thank you! Scott F. here today>
Sorry to bother you again!
<Never a bother, my friend!>
But my queen Angel as stopped eating two days ago! (can he stay a lot of time without eating??) and  seems to have cloudy eye and also the eye membrane seems to be damage going out a little bit still but less than before ,also a notice that his eyes are a little bit red ,and he also had like blood behind the lateral
fins, but it seems that it is healing now (white covering it) also have white spots on the fins!!! but doesn't look like ich, he always hiding, but he is breathing normal !!! My nitrate was a little bit high, but I did a water change of about 30% of the tank (125 gallons)  and it is now ok.
<Good decisive move!>
All the other fish are fine. I wouldn't want this to spread to the other fish. Maybe  environmental disease?
<Hard to say from here, but it may be a (secondary) bacterial infection of some sort. It may have been brought on by lapses in water quality, an injury, or some other trauma.>
Should I move him out of the tank and use medication? If yes what should I use that is easy to get in almost all fish stores? I don't want to loose it. Thank you in advance and also HAPPY NEW YEAR! And again, thank you for your help! Your web site is  helping me a lot and I am sure a lot of aquarists, also! Continue the great work!!!!
<I think it is time to move the fish to another tank for observation and treatment. I'd probably try a broad spectrum antibiotic, such as Maracyn Two in the treatment tank. Please note that antibiotics can interrupt nitrification in aquariums, so be sure to supply mechanical and chemical filtration in the treatment tank. Do keep reading on the wetwebmedia.com site to see if you find descriptions of any disorders that are similar to the one that your fish is experiencing. Good luck! Regards, Scott F>

Save The Queen! (Sick Queen Angel)
Hi,
<Hi there! Scott F. with you today!>
I just moved my two fish to a hospital tank for treatment of ich.  The queen angel is looking the worst, rapid gilling and signs of excessive mucus.
<Hmm...could be a sign of Amyloodinium, which is a very aggressive parasitic disease, or possibly, a response to an environmental trauma of some sort...>
I have a good level of copper in the tank, but I'm wondering if I should give a freshwater dip or if it would be too stressful on him.  If I leave him in the tank and just wait for the copper to show its effects on the disease, I'm worried he may not last that long.  What do you think?  As you can imagine, this is kind of an emergency, so thanks for your reply. Tim  
<Well, if you also see a very fine "haze" of spots on the fish, it may very well be Amyloodinium, which can kill with horrifying rapidity if left unchecked. Do a quick scan for information about this illness on the WWM site, just to make sure. I would, however, check all "basic" water parameters ( pH, ammonia, nitrite) to verify if there is no environmental cause for the reaction that you are witnessing. I'd also check your copper level in the (treatment?) tank, to make sure that you did not overdose...Very important to measure when utilizing copper for a disease treatment. If dosed improperly, you could do more harm than good! Finally, I think that freshwater dips, properly executed, can certainly help with parasitic diseases. They should be used as a supplemental therapy, IMO, in conjunction with a course of copper sulphate at proper therapeutic levels. Decisive action is important with this illness, so if it's Amyloodinium, you did the right thing...Just keep a close eye on things, and be prepared to take further corrective actions as they become necessary. Good luck! Regards, Scott F>

Precious Fish Passed Away, But He Did His Best to Save It (4/5/04)
  Hi there again Crew! <Steve Allen tonight>
  Lost my prized queen angel....Gutted! And feel like giving up and forgetting about reef tanks etc. <So sorry for your loss, but hang in there.> I have gone around 4 years without any diseases at all. Including bringing back a yellow tang with terrible HLLE to a plump healthy beautifully coloured individual. <Good work. You have proven your abilities.> Have a couple of questions to ask you if I may? <Certainly.>
  The only two signs something was wrong with the queen was increased respiration rate + refusal of any food. <A sure sign of disease.> I am not one usually given to knee-jerk re-actions, but
in this case I knew I had to do something quick. I moved the queen to a hospital tank (with the water taken from the main display) and began treatment with copper. Now I know the queen (as are most angels I believe) are fairly intolerant of copper but as my bat was definitely suffering from Ich ( they were in the same tank) and until I QT'd the bat 4 days ago, I presumed that the queen had an infection which at this time was confined to the gills. From the first sign of distress to death was a matter of around
30 hours......Have you any idea if there was any other form of treatment I could have given? <Formalin can be a great alternative. It may not be the copper that killed the fish. Gill infestations are rapidly fatal. Angels have been successfully treated with proper copper dosing/levels.> Did I do the wrong thing? <Now> Should I have done FW dips? <FW or FW/Formalin dips are effective, but so is copper. Aggressive therapy was indicated here.> Should I not have used copper? <I do not think this was the big mistake you worry that it was. Something else may have been better, but I think your fish died because its gills were affected by the infestation, not due to your copper treatment.> There are still 4 fish left in the 6x2x2 should I remove them all or can I
leave them until maybe 2 months has gone bye and after this time assume the disease has gone from the tank (The idea behind this being that if no other fish are infected then the Ich has not had a host?) or am I daft to think this? <It could still be lurking sub-clinically as long as their are fish in there. Have you any theory as to where the ich came from? I'd say the safest approach would be to quarantine and treat them (hyposalinity and increased temp, with copper or Formalin if signs/symptoms) to be safe. Leave the main tank fish-free for 6 weeks or so for the parasites to die out.>
  After going for so long w/out disease I guess I got complacent and put one piece of live rock straight in the main tank and from there on lost half my fish. <More evidence to support the prevailing WWM view that all living things be quarantined, not just fish.> Anyhow from a fed-up (and now very broke) aquarist of many years I wish you all a good day. And hope to speak to you again soon with some better news. <We look forward to that.> With many thanks. Simon <Don't give up yet Simon. Your techniques are fundamentally sound. Do the QT/fallow to be safe and then think about a new fish to add down the road. Nothing can "replace" a precious/beloved animal that dies, but you can find another to cherish in its own right some day. Good luck to you.>

Queen Angel Coloring Cont'd
Dear Ryan"
<Eric,>
I FW dip the queen angel, and right when he is at the FW a lot of white little "stuff" flying out of his gills and fins, he instantly open up his gills again and start eating those white stuff back!... strange... I figure that would not be good so I change the FW and dip him a little longer, then back into the QT... 1 day later he is breathing normally again, fins is all cleared and is eating/swimming normal. However, the color issue is still present, but not at night when the fish is
asleep... (When I check him out at the middle of the light his body is uniform in color...)
<Hmm...I'm sure you already know that Angels of this difficulty are easily infected with parasitic and fungal diseases.  I would certainly keep dosing with Formalin (if you already are), and continue the FW dips.>
What would probably be the stuff that flies out from his gills?? Those stuff like expanded when coming out of the fish's gills.. It's soft, milky white, circular to the human eye... <Sounds fungal, but if you send a pic I'm sure that Bob/Anthony can verify>
If now the fish is all well, should I treat it with any medication just in case?? <Yes, Formalin ASAP>
Lastly, will small puffer (dogface) eat coral and cleaner shrimps that
larger than itself? <Yes, and likely choke to death in the process.  I wish you the best of luck getting this animal healthy!>

Queen Angel... health  - 5/18/2006
Hi Crew,
  I recently purchased a Queen Angel and have him housed in my 200 gallon FOWLR Tank. He has been in the tank for about three days now and have not started eating yet but he is swimming around. This morning I noticed what looks like his intestines sticking out of his rectum and after about 2 hours it seems to have gone back in. I was wondering what could have caused this and what am I to do about it?
<Mmm, not much other than hope for a self-cure. There are such causes for "prolapsed colon" condition that can be parasitic in origin, but these cannot, should not be addressed with chemical treatments in the short term. Bob Fenner>

Need help with a queen that's flickering and scratching    4/16/06
Hi there ,
  I looking for some advise on what to do if anything with  my queen angel.   I have a 4 inch queen in a 125 for about a  month  now and she's been doing great and eats like crazy.  I noticed yesterday that she's been flickering/shimmy once in a while .
<Is a normal/natural behavior to a degree>
  I also noticed her rub here mouth or face against the rock and some ornaments several times .  She has no visible signs on her . My water parameters are fine .  (0 ammonia, 0 nitrite, 8.3 ph, and nitrates usually kept around .10).  I'm debating whether to do anything right now or wait?  
<I would wait>
I was thinking of giving a freshwater dip for a few minutes then a 1 hour bath in saltwater with methylene blue or Para guard (SeaChem).  I also have something called "quick cure" which has malachite green and formalin but I've never used this product.
<Is mentioned on WWM, is toxic...>
   By the way I've been running a  15 gallon QT tank for about two weeks now .  there's are two perculas in there right now.  Your advice is well appreciated.

Re: need help with a queen that's twitching and scratching***update**  - 04/19/2006
Hi there
My Queen is still twitching and rubbing against objects in the tank though she still has no visible parasite signs and is eating very well.
This has been going on now for six days so I'm getting worried its only going to get worse and I want to do something before its too late.
<I would not "do something" here>
  As stated previously, I have a 15g QT that's cycled and been using water from the display tank with a penguin BioWheel/   I was considering giving her a  5 minute fw dip with either methylene blue or quick cure then moving her to the qt .  While in qt , which chemical treatment would you recommend ?
<... none>
Cupramine, CopperSafe, ParaGuard or methylene blue?
Also since I shouldn't be using carbon in the qt , how often do I need to change the water?    
Thanks
Peter

Hyposalinity...   4/18/06
Bob
  thanks for your quick reply . just one other thing. A friend suggested to lower my salinity to about 1.016   I previously had the sg at 1.022 and its now 1.020 after yesterday's water change.   Would lowering the  sg to 1.018 help at all in eradicating a parasite and is it a safe and comfortable level for a queen angel.  She still eating a lot but the shimmering and scratching hasn't stopped .    thanks
