                                                            Nitrate..............0ppm
                                                            pH....................76.......

8. What kind of waterconditioner are you using: using filtered water

9. Do you add beneficial bacteria: no??

10. Symptoms your fish is showing: red cap only has growth on eye and  head is discolored and irregular (even for a red cap) Tail fin was the first thing we noticed looked like it was disolving, that is why we thought tail rot. That occurred about a year ago and we thought it was just going to take time to grow back but now she is getting worse.

11. Since when does your fish show these symptoms:   1 yr but has gotten much worst.  
We have as several pet shops and treated fish for fin and tail rot as they suggested 4 or 5 times with no change.  No one at the pet shops can help we have tried everything they said til we were afraid to over med too much.  
 

12. How is the normal behaviour of your fish: stays at bottom and sleeps all the time. Just gets excited when we come to tank and talk to her. then she goes up and down like she is trying to go to top.

13. How do the other fish behave: normal

14. Post pics of the sick fish:yes

The best thing to do right now is post the results of ammonia, nitrite and nitrate asap.

If I were you, I would take your fish to a veterinarian that will treat aquatics.
Your fish has an overgrown wen, interfering with his eye sight.
He has a fungus and probably a bacterial infection causing tail and fin rot.
He needs specialized treatment that no one can help you with on here.
He is very weak and looks like he also has some swim bladder issues.
You cannot keep healthy fish changing the water only once a month by guess and not testing it.
Good luck with your fish, I hope you can find help for him in time.
The only other alternative is to put him down or have him put down, humanely.

April hun don't think minde meant anything against you. She just see this fish in bad shape. Blondie has tried to treat it with no success for a year and maybe it is best for the poor guy to be put to sleep to end his and the owners suffering. I am no expert Blondie but I think even if your baby could be healed it will be a long and painful process and i think this is where minde's thoughts are also. I had a fish with a overgrown wen slowly stop getting around and seem to kindof give up because it couldnt see. Alot of large wen fish live fine even if become blind by it but others don't. Someone told me the more stationary a fish is the more prone it is to infections. If you decide to euthenize Clove oil which i have been told you can get over the counter at pharmacys is most humane way if you so decide. Another option people do it put fish in a bag or container with its own tank water and put it in freezer this is supposed to slowly put fish into hibernation then they fall asleep and freeze. Clove seems to be best option if you can get it around you. Now if you decide to treat tomorrow morning there is a fish pharmacist that will answer all question for free at fishyfarmacy.com 1-520-298-7814. They can help you with anything fish illness and they won't push their products on you unless needed. Good luck hun!

Wow, this is a great price on this Master test kit by API.
Thanx, Pappyfish for posting this link.
Now I know I can get the API test kit at Walmart which is near me.
The petstores are alot further away!

No she didn't it is just me being a fool again, I'm no good at this I'm sorry. Take care

Is ammonia 25 ppm or 0.25 ppm. 0.25 ppm can cause ammonia burn but 25 ppm can kill your fish in minutes.

How are you changing that much water at a time? Are you leaving your fish in the tank during the process, or do you just empty the whole tank and clean it thoroughly?
The best thing you can do about the ammonia is to start changing about 40% every week, and testing the parameters every day!
If you notice the ammonia slowly going away being replaced by nitrite, you're on the right route

However, this fish doesn't look very healthy at all, I'd definitely bring it to have some of the wen removed, it's growing far too big.
And the fin rot seems to have developed quite badly, so you really need to start working on getting the water in order so that you can start treating asap...! If you have a cycled quarantine tank, that would be ideal!

Oh also I could never put her down.  If you would see how excited she gets when we come near the tank she is a happy fish even when she is sick.  This is why all the pics are blurred she swims all around when we are nearby. 
She has always had some bladder problems that is very typical for rec caps but when I give her the peas that takes care of that.  It got so bad a couple years ago that she could only swim upside down, it was so sad but the pet shore once again had no answers to I found out about the peas online too. We have had her about 4 yrs.

Thanks to all who helped me and made suggestions!!!

I have read about the bladder problems so much also in certain goldfish varieties.  Diet is the key there from what I have read.  

I'm not any kind of expert at all, I'm a newbie myself trying to learn as much as possible to keep some healthy and happy goldfish.  I really hope you can get that fishy healthy again.  Sounds like you care a great deal for her.  Welcome to the forum Blondie!  

Blondie i called the fishyfarmacist he said it could be something called lymphocystis virus. now this is based on my discription from the blurry picture. It is free to call him. You can look that illness up it is incureable but he said he has seen fish live years with it. It is contagious to your other fish if it is that. Here is a site i found with discription and a picture at bottom of the virus. (Link is not visible to guests. Please register to view.) He also said to be careful because we are unsure what this is and some of these goldfish illnesses are bad for humans too. I hope this helps and i would recommened calling him if you have any questions its the phone number i put on my last post on this thread. Hope everything works out.

Thanks and yes it was .25 test was light yellow with a slight tint of green.  ??

Thanks again for all the great advise.  And for the record we did take the water to the pet shop several times and they said it was in normal range and we did treat with Melafix many many times.  I am just not sure these kids at the petshop knew what they were talking about. or if the water was tested properly.  I worked at a pet shop for about 5 years thru high school and college and I never recieved any information on sick fish.  I knew what ick was and that was about it. That is because our fish there got it.

So to everyone maybe a petshop is not the best place to find out.  this forum looks like a much better solution.

If melafix isn't working, stop using it!! Yes it will only work in perfect water quality but if any medication had no effect on the fish, I think you should stop using it and try something else. This is what you would do for yourself, right?

I think calling that number Aimee gave you would be great, these people know what they are talking about unlike id*ots in a general pet shop. Hanna also gave alot of great information, please read it carefully and act on it. I can't help with the wen thing, that is why I think you should call that person and/or follow Nossie and Minde's advice.

You also have to work a bit harder to fix this swim bladder problem, yes it is common but it also should not be happening and you should be working hard to fix it. Do you always feed them a variety of food? Have you tried epsom salts?

Lol glad I am not only one who thinks melafix and pimafix pretty much useless once a fish really sick. I meant to ask the pharmacist what he thinks of them but forgot. Will ask him next time.

Hey blondie how is your fish? Any improvement or any worse?

Nossie, I've learnt that too Definitely agree with it then as I've seen stuff heal by itself or with a water change which I would have in the past treated with melafix and pimafix. They are good for wounds and slight symptoms as you explained. I reckon aquarium salt is often better to use for the things some people would use melafix and pimafix for
