Goldfish Success
What it takes to keep goldfish healthy long-term

by Robert (Bob) Fenner

New fish owner- sick goldfish     9/26/14
Hello,
<Hello Christina,>
I checked your FAQs first, but did not find a post that I was sure addressed my issue.
<Really?>
My veiltail goldfish (Norman) has a white/see-through growth on his head (more cotton than waxy). I thought it would get better when we bought him a 20 gallon tank, but it is still spreading.
<In all honesty, 20 gallons is too small for Goldfish, and certainly a potential source of problems once they're above, say, 8 cm/3 inches in length.>
Initially, he developed a blood red spot on his head that cleared up after every water change, but came back after about 3 days. He has not had the red spot since we bought the new tank, but now the white patch has grown near the same area and spread to his entire head.
<Likely an ulcer of some sort, with a subsequent bacterial infection spreading outwards. Irritation causes mucous production, and dead skin goes white. Could well explain the symptoms.>
Please help. He is active and eats fine. No other fish live in his tank and I use My veiltail goldfish (Norman) has a white/see-through growth on his head (more cotton than waxy). I thought it would get better when we bought him a 20 gallon tank, but it is still spreading. Initially, he developed a blood red spot on his head that cleared up after every water change, but came back after about 3 days. He has not had the red spot since we bought the new tank, but now the white patch has grown near the same area and spread to his entire head. Please help. He is active and eats fine.
<This is a good sign.>
No other fish live in his tank and I use well water to fill it. I do a 30% water replacement every week and his tank also has a filter.
<Good. But do review water chemistry (hard and alkaline is best).>
I do not know his age. Any idea what this could be and how I can treat it? I have attached some photos.
<Well, they didn't come through.>
Any help would be greatly appreciated. We love our Norman and I would hate for him to suffer due to my inexperience as a fish owner.
<Do start by reading here:
http://www.wetwebmedia.com/fwsubwebindex/goldfish101art.htm
My first action here would be to get an antibiotic or antibacterial medication, something fairly general like Seachem KanaPlex or the popular combination of using Maracyn 1 and 2 together (the two products treat
different bacteria, so used together, work even better than singly). Avoid tea-tree oil medications like Melafix that promise a lot but don't consistently deliver. Do test water quality regularly, any nitrite or ammonia above zero will be a problem. If in doubt, buy a bigger filter:
Goldfish are heavy polluters, so a filter recommended for a 20 gallon tank will be insufficient for a 20 gallon tank because such a filter is actually designed for small fish like Guppies and Neons. Instead buy the model a size or two up the range, so a 30 or 40 gallon filter for a 20 gallon tank.
If necessary, adjust the flow rate to avoid too much turbulence, but otherwise a bigger filter will always be better. Cheers, Neale.>

To sanitize or not sanitize?      7/21/14
Background: I have a 50 gal freshwater tank (with a 70-gal canister filter)
that happily housed three goldfish until we moved about a year ago. When I set up the tank again, I struggled with water quality issues/bacterial infections (I assume, based on the symptoms) and ultimately lost the goldfish.
<Yikes; am wondering what the cause/s were here>

I know goldfish have their challenges--which is why when I decided to start again with new stock a few months ago, I went for tetras to start. Things were stable for a while, then I started losing them with similar symptoms: general lethargy followed by difficulty swimming, no signs of external parasites. On advice of the local aquarium shop guys, I treated the whole tank with a broad-spectrum antibiotic to try to kill whatever bugs were lurking.
<Mmm>
That worked until a few days ago, when another tetra died following a similar pattern. This is getting to be pretty crazy-making for me, and I imagine the fish aren't especially thrilled either.
At this point, I'm contemplating breaking down the whole tank and trying to sterilize everything, which brings me to my question: should I?
<Possibly; do have some fish-friends come by and look... am wondering if there's something toxic in your system. Perhaps a geode... or metal containing something>
And if so, what method would you recommend to make sure I really, really get all the bugs--
<Bleach washing... here is an SOP: http://wetwebmedia.com/clnornart.htm
The same procedure applies for sterilizing a complete system. DO read through this thoroughly and get some help... Take CARE to not splash bleach on you or the surroundings>
because the only thing that might make me crazier would be going through that monumental effort and then having the problem crop up again.
Final note: current stock is 7 tetras, one angelfish, water parameters are good last I checked, and I do 25% water changes every 2 weeks.
Thanks!
<Ah, welcome. Bob Fenner>

**I'm willing to try that again as an alternative to bleaching. I don't want to lose any more fish, but (aside from the epic work of taking apart the tank) I'm a bit concerned that I'd just be swapping one problem (possible bacteria) for another (non-cycled tank, stress of moving fish).**

**Interesting thought. I have had the same things in the tank the entire time I've owned it (4+ years) with the exception of the heater and thermometer I bought when I got the tetras...unless something was
introduced inadvertently during the move (can't think what that would be?). Any input on what sort of symptoms would I be seeing in the fish if this was the case? Would they be any different than what I might see with an internal bacterial infection?**
<<Not necessarily... and there are such things as "olde tank syndromes"...
What seems to happen as systems age, they become more depauperate (less speciose) and even toxic; with some few microbes overpopulating and poisoning their own world w/ metabolites... An important human lesson as well>>

**Thanks for the link, a couple additional questions about bleach washing an entire system: Would you recommend bleaching the gravel I have for the tank bottom, or dumping it? What about the ceramic rings in the canister filter?**

**I checked the water parameters again and notice that the pH is a bit elevated (7.6 maybe?). Could this be the issue?**
<<Not likely; unless it's wildly vacillating (too little alkalinity).

lump on a shebunkin... Rdg.       7/19/14
Help!
<Vic>
We have an otherwise healthy shebunkin about 4 inches long, living alone in a 55 gal aquarium with 2 strong filtration systems and 2 water changes a month.
He developed a large lump on his side that slowly protruded more and more.
At its peak we saw a few wispy spider web like strings coming from the lump, about 1 or 2 inches long.
<Umm; water quality tests?>

Later the lump erupted and stuff that we could not identify what protruded a little bit from the wound. but it quickly receded and healed up and now is completely gone. But then maybe 2 weeks later it started happening again in a different spot, closer to the head, but still behind the gill. The bump is now very obvious and the fish seems to be slowed down by it somewhat.
No wispy strings seen yet, looks like it may erupt soon.
<Foods, feeding?>

The closest I can figure from online research is anchor worm, but it doesn't quite look like anchor worm. I ordered a commercial anchor worm med and was about to try it when we decided to give you guys a try.
Is this a parasite that will be treated by anchor worm meds, or is this a bacterial infection that requires an antibiotic?
Regards,
Victor

Question About Goldfish... no data    6/17/14
Hi,
I found this e-mail address at wetwebmedia.com, and I was hoping you could help me.
<Will try>

11 years ago, I inherited a comet goldfish from my grandfather who passed away. My grandfather had the fish for awhile, so I’m guessing the fish must be at least 13 years old.
<Ok>
The goldfish has always been very healthy up until last year, when he started having buoyancy issues every now and then after eating.
<... likely mis-fed too much flake/dry food... have you done any searching, reading on WWM?>

We adjusted the way we fed him though, and the swim bladder issue seemed to be resolved.
<...>
Then, a few months back, the nitrate level had crept up,
<? To what level?>

and my goldfish was laying on his stomach on the bottom of the aquarium. We resolved this issue by doing frequent water changes and testing the water everyday until the nitrate level was brought down. Since then, he had been back to normal until a couple of weeks ago when his swim bladder issue returned.
<... need to tell you; there is no such thing... environmental stress is the root cause.>
We assumed he would only be bloated for a few hours like he used to be, but after an entire day of laying upside down, we realized something was wrong.
We noticed he hadn’t been expelling waste so we assumed he was constipated, and fed him peas for a couple of days. During this time however, the area around his anus had become swollen and red and the scales were sticking out. It appeared to be dropsy, so we treated him with a little Epsom salt, and the dropsy went away very quickly. He was able to excrete as well, but he still had buoyancy issues, and his back end still looked very full or bloated. We searched around online, and went to a fish store near us, and it was decided that he probably had some kind of infection.
We bought an antibiotic for the goldfish at the fish store, and the after one dose he appeared to be 100% better. The next day however, he didn’t look as good, but we continued the treatment as directed. From there, his health has declined, and he now spends a lot of his time curled over on the bottom, and although he seems a bit off balance at times, can still swim and eat normally like he used to.
My biggest concern right now, for which I can find no answer, is a symptom that developed just this morning. The underside of his jaw is now protruding. I don’t know what caused this, and I don’t know if he’ll be able to eat tonight when I feed him. He didn’t have it this morning when I first woke up, but just before lunch I noticed the underside of his jaw sticking out. He also appears to be breathing a little more heavily. Is there anything I can do for him? I’d like to help him if possible. I’ve attached some pictures of the underside of his chin for you to look at.
Thanks in advance for any advice you can give me!

Question About Goldfish... no data    6/18/14
Sorry. I thought it would be useful to include his health history. However, my main question was just regarding the underside of his head. If you haven’t seen that before though, it’s okay. I just wanted to know if it was serious or if it could be treated at all.
<Can't be treated... other than improving the env. and nutr. as previously stated>

I’ve taken care of the fish for 11 years now, so I’m familiar with the information on the page you’ve sent. I’m sorry I’ve taken up your time.
<Why I/we're here; to help if we can>
I just haven’t found any answers elsewhere on the internet, so I thought it’d be worth a try to ask. Thanks anyway.

Moor goldfish fish missing eye   6/17/14
Hello,
I was feeding my fish and I notice one fish was missing his whole big eye.
We have cats in the area so that might have caught it. It seems a little weak and slower than usual but I don't know what I should do Thank you,
Jessica
<Remove the source of the trauma... and keep on w/ regular maintenance. Can live w/ a single eye.

Mystery White Things On Tail Fins; no data     6/16/14
Hi. This morning I noticed some mysterious white things on the low tail fins of my Oranda's fins. The fins are also crinkled looking. Not smooth like usual.
<I see this, these... usually either evidence of a physical trauma (bending, breaking of fin spines) or resultant from some aspect/s of poor water quality (of course aided by genetic, nutritional inputs)>
I have seen Ich before.
<Not Ich>
It dose not appear to be any sort of Ich I have seen before. I have seen fin rot too. It dose not appear to be fin rot that I have ever seen before.
I included some photos where you can see the mystery white things on her bottom tail fins.
My fish will sometimes rest on the bottom of the tank for some reason, if this helps.
Here is the best picture of the strange white patches.
If not Ich or fin rot, what do you think these white patches could be?
Bacterial? Carp pox? Any help here is appreciated. Thank you.
<Water quality tests, maintenance, foods/feeding...? Bob Fenner>

Please help!! GF rdg       5/30/14
Hi please can you help my little sweetheart Cream, who seems to have problems passing faeces.
<Looks fine in these pix... I might try a bit of Epsom Salt... search/read on WWM re. Bob Fenner>
This has been occurring for a week. The tank is cleaned once a week with a 15% water change.
Any help you can offer would be gratefully appreciated.
Ps. Sorry for quality of photos Cream likes hiding!!
Many thanks

My goldfish is really bloated.      4/3/14
I cleaned the tank recently and the next day when I went to feed them I noticed he was looking a little bloated but it is getting worse. There are three other fish in there. These fish have been together for four years.
The tank is 15 gallons and it has a filter to clean a 20 gallon tank. He is acting like he normally does. And eats as usual. I am getting really worried. He is getting so bloated it looks like he could pop.
<Could I direct you to following articles:
http://www.wetwebmedia.com/fwsubwebindex/gldfshmalnut.htm
http://www.wetwebmedia.com/fwsubwebindex/goldfish101art.htm
Both will answer your questions, tell you what you need to do, and provide you with a checklist for proper care -- for example, 15 gallons is too small, crazy small if there are 4 goldfish in there! Cheers, Neale.>

Sick Black Moor. reading...     4/1/14
So I bought my new black moor on Friday and now it looks like this. I'm not sure what's wrong and I'm starting to worry about it. Can you tell me what's wrong or what I should do?
<This poor chap is in a very bad way! I'd do two things here. First I'd medicate as per Finrot, using a reliable medication (not Melafix, Pimafix, or anything else involving plant extracts). Here in the UK my recommendation would be eSHa 2000; in the US, Kanaplex or the Maracyn + Maracyn 2 combination seem very highly regarded. Next up, I'd add salt to the water, at a dosage of about 2-3 gram per litre of water (that's about 0.4 oz per US gallon). I'd also raise the temperature a couple degrees. Salt/heat work well together against Whitespot, which my guess is the "key" that unlocked the door to massive Finrot and other bacterial infections of the skin. So dealing with both the Finrot and the Whitespot will be helpful here. Goldfish have a high tolerance for salt so don't worry about causing stress using salt. With a bit of luck, this chap should recover without problems. Meantime, do read here:

Gold fish emergency... 12 MEGs of nothing useful   3/22/14
<Why have you exceeded our file size requirement... sending 12 Megs?>
I have had an orange fan tail gold fish for 2 years. He has a very large tank - 13" x 19" x 23" and is the only fish in the tank. It has a good sponge type filter.
<This is neither a very large system nor a good solo type of GF filtration.

HAD you followed directions, and searched, read ahead of writing; you would know this>
He always had a small slightly red spot on his head but it has developed into a white sore on his head. (see photos) And, the sore develops clear blisters at times. He eats and seems to be ok but weak. I can't keep the filter on too long or he stresses and hides under a plant since the current is stronger than he is - one time he got sucked onto the intake of the filter.
He has also had swim bladder disease
<There is no such thing>

which after I feed him peas he seems to do better.
Please help.

A request for advice - sick Black Moor Goldfish   2/25/14
Hello There,
<Karen>
I¹m looking for advice on a taxing problem I¹m having with my pet Black moor and Oranda goldfish and really hope you might offer some help.
<Let's see>
More than six months ago the Moor began showing soft white spots on her anal fins. (Pic of the Moor attached)
<I see these... quite common... many folks attribute to physical trauma/injury... with the white areas being sites of regeneration/decomposition. But I consider that other factors can often be implicit... e.g. water quality and nutrition>
 A few months ago the Oranda started to show very small spots of a similar nature on his anal fins as well.  If left
untreated it spreads.  It doesn¹t look like Ich to me as the spots aren¹t granular. Other than this, they are not showing any other symptoms of illness. They are offered a varied diet and are quite active.
<Ah, not parasitic I assure you. I've dissected many, make that MANY goldfish... for demonstration, classes, lectures in fish pathology>
I¹m pulling my hair out trying to solve this problem. These fish are around two to three years old and are in a 45 gallon tank with an oversize Eheim filter. I do weekly 50% water changes and a filter clean every 4 to 5 weeks.
I try to keep the tank very clean.
<Ahh, I do like the Eheim canister line (have used it myself for decades); but I would add another (outside, hang-on power filter; one with activated carbon inserts) to supplement the filtration, circulation/aeration here... could be simple DO issue here at play>
Generally my water parameters are good. Current numbers are Ammonia 0, Nitrates 15 ppm (this due a Tetracycline treatment I tried and just finished), PH 7.7 (again higher than normal due to the Tetracycline),
<Keep your eyes on the ammonia, nitrite here>
Nitrites 0 ppm.
I don¹t heat the tank so water temperature can range from 68 deg. (lowest in winter) to 74 deg. (highest in summer).
<I'd add a heater, set it low...>
With advice from the fish folks at my LFS and other online hobbyists, I¹ve salted the tank (1 tablespoon per 5 gallons) and tried Pimafix, Melafix,
<These last two are more probable as issues than any help>

Fungus Cure, Furan 2, Tetracycline and PraziPro. The treatments of Fungus Cure, Furan 2 and Tetracycline reduced the spots by didn¹t completely clear it. Once the medications are out the spots come back and increase over time.
The meds have completely cleared the Oranda but the spots have come back on him minimally twice.
<Again; these markings aren't pathogenic... not caused by a biological agent. Simply improving the environment, nutrition will cure the marks>
After each treatment, I¹ve made sure to clear the tank of meds and give the fish a break for a week or two before attempting something else.
As I mentioned, I just cleared the tank of two rounds of Tetracycline. I started a third treatment but the nitrates and PH started rising and the fish started to look stressed.
I recently spoke with an online vet tech and she suggested that this issue could be Cotton Wool Disease.
<? From what cause? Again, environment>
 She directed me to add salt back into the tank (I¹d pulled it out as they had been in it for a number of weeks), do a 50% water change, wait a few days and then try Mar-oxy. If that doesn¹t work, try Maracyn II. I did the water change last night and added 1 tablespoon of salt per 5 gallons of water.
<See WWM re the use of salts: generally overrated>
I¹m at the end of my proverbial rope here. I can try these two meds, but would really like another opinion before I subject them to yet another treatment. I feel like I¹m just taking another shot in the dark and it¹s certainly not good for the fish to be subjecting them to more medication that isn¹t targeted properly.
I would really appreciate any information you might be able to offer. This little black fish and her companion have become quite dear to me.
Thank You, Karen Sibley
<Add the outside filter, more roughage to the diet.... See WWM re GF fdg. as well... And in a few weeks you will see improvement. Bob Fenner>

Bubble eye goldfish . – 02/20/14
My goldfish has white on his pupil almost covering it all. Not on the outside of his eye that's clear. It's inside the bubble as it were. What could that be? Perameteres fine and have 2 fish in 250 litre aquarium.
<Hello Mark. Please let me know what "parameters fine" means. What's the ammonia or nitrite level of the water? The hardness? The pH? How is the aquarium filtered? How often do you do water changes? Damage to the surface of the eye (which is what's going on here) is typically caused by physical damage and/or poor environmental conditions. So supplying me with these data will make a more effective diagnosis possible. Meantime, read the link below and follow the links therein to sections on disease, trouble, and so on.

Twisted, sinking, spiraling goldfish... The usual      1/22/14
Hi, I was hoping to get some help with my sick goldfish. He's (no idea if it's really a 'he', but anyway) a standard goldfish shape,
<Yes, a "comet" variety>
although is a brownish silver colour rather than gold. The only one like that in the pet shop, so I bought him! I tend to think he is some kind of throwback or hybrid, having this drab colour. He's been in very good health for three years.
<Though greatly stunted: "Bonsaied" from being kept in a small volume, waste product accumulation limiting its/their growth>

There are three more standard goldfish in the tank (of 65litres), two around ten years old and going strong. The other is about three years old with no problems. The fish are all three inches and under.
65 litres is about 17 gallons, which I now gather is rather small for four fish.
<Ah yes; esp. this "variety"/sport>
 I change about half of the water fairly regularly and have a decent filter (Fluval 2 plus). I'm afraid I don't routinely test the water chemicals.
<Am sure Nitrates are "through the roof">

I know the tap water here in Scotland is supposed to be particularly soft, which I had assumed was a good thing but maybe not.
<Simple to read on WWM, elsewhere... goldfishes prefer harder, alkaline waters>

About two weeks ago he started swimming on his right side occasionally, then about a week ago it was most of the time. Since then he's developed a permanent sideways twist in his back, causing him to swim in a spiral. I thought it might be swim bladder, although I gather this is rare in the non-fancy types. In any case I've recently cut down on the flake food and
been feeding them first bloodworm from the petshop and, more recently, chopped-up peas. I also recently picked up some 'Interpet fish health treatment 13- Swim Bladder treatment'. Nasty stuff I think. It's four doses at 4-day intervals, so far only the first has been applied. I'd hate to be giving this medication unnecessarily, as I'm sure it's a shock to the system.
<Yes; and of no use here>
He's still in the tank with the other fish, who aren't bothering him, and he seems just about able to feed but spends a lot of time propped up in the weeds or on his side at the bottom (he's prone to sink rather than float).
A few times I thought he was dead but he's still pretty lively (though uncoordinated) when the food goes in.
If anyone can think of anything else I can do I'd love to know. Is it likely that the fish will recover from this handicapped state? I've seen advice to euthanise a sick fish but I can't countenance that right now. I seem to remember having a bent goldfish for some years when I was a child, which adapted to its injury and (I think) even reproduced.
Many thanks for any advice,
David

Re: Twisted, sinking, spiraling goldfish      1/22/14
Many thanks Bob. 'Bonsaied' pretty much describes it. I'm going to see if I can re-home a couple of the fish, keeping just the two old ones.
<Ah, good/better>
I inherited these fish from far worse (unwanted pets in a tiny tank with no filter) living conditions, but it's only now dawning on me just how much space and care they need to properly thrive. I'll consult the forums and sort out my act regarding water quality too. Thanks again,
David

Bob Fenner is a life-saver! Just an update, and another big thank you for the timely response. You've done me a very great service, and I realise it must be frustrating to get asked the same questions you've covered in the general articles and FAQ's (as in my case). I think the following short account will come as no surprise to you.
Once I checked and corrected the Nitrite and Nitrate levels (which were at around 3 and 80 by the reading I took. I got them down quickly using a Poly-Filter) in the tank, my sick goldfish -which by this point had seemed not just at death's door, but frequently looked dead for long periods- made what seems like a full recovery within 24 hours.
I realise the long term health of all my fish will have been affected by the toxicity of the undersized tank, but I will do better for them from now on. Can't thank you enough.
<Ahh; the pleasure... Thank you for your follow up. Life to you David.
