Sick Goldfish... Possibly Fungus?

Hello, I had posted here a few months ago about a common goldfish which had been rescued from a fair and a fancy goldfish who were both spending a lot of time at the surface. ?They are in a 30 gallon tank which they have been in for about a month or so. ?The fancy goldfish has been fine, but the common has been getting worse and worse.

First I noticed some fraying of his tail fin, and seemed like possible fin rot. ?He also had a white "ring" around his middle section, but it was so thin that it was only viewable when looking at an angle down the fish. ?He started spending a lot of time on the bottom of the tank, but was able to be active when fed etc, so I was concerned about possible parasites, as that is what some websites online stated could cause that type of activity. ?The person at the petstore knew little about fish, and I bought "aqui-sol" for parasites, and admistered a day or two of dosing with that. ?The owner of the petstore, who apparently does know more about fish, finally was able to call me and speak to me directly, and he thought the problem was fungus. ?I purchased "fungus eliminator" and used it once on the tank. ?There was no noticable difference after several days, and the common was still spending almost all of his time on the bottom of the tank, so I decided to perform a salt dip (a process I know little about, but read about somewhat online.)

I filled a 10 gallon tank partially?to?about 6 gallons, using a?combination?of water from their tank?and fresh, treated tap water.??I?used?about 2 cups?of non-iodinized salt, slightly less than the 1/2 cup per gallon as recommended, due?to the small?size?of the?fish (1 1/2?inches). ?I later realized?most?of the salt?did?not disintigrate. ?Using?a goldfish bowl as?a taxi, I took the common from the 30 gallon tank and place him?into the salt?dip tank?for about 45 seconds.??After returning him?to the 30 gallon tank, I?noticed that he?no longer stayed?on the bottom, and actually stayed?closer?to the?surface.??For several days, he was?not?immobile?on the bottom at all. ?Then the real problems began.

He began to spend his time on the bottom again, or close to it -- in an ornament; a trophy/treasure type sculpture fish ornament with an open top and open side. ?After seeing him spend almost all of his time in there, resting on the bottom, for a few days, I noticed that his tail was almost completely white, and appeared fuzzy. ?His top fin has also been completely?clamped?and?is very red, streamlined against his body as a red line. I noticed the very back?of?his tail, behind the?white, to?be turning brownish.??

I do not know if the salt dip helped or hurt, or if I should do another. ??I also just yesterday used "fungus clear" tablets as an alternative since it had been roughly 4 days since the other fungus treatment and since it had not worked.

Is there any hope for this fish? ?It seemed to me like they wouldn't be able to regrow damaged fins... and his tail is looking horrible. ?Is there any way to help him, or is he already too sick? ?Thanks for your help.

Some more details....

For a long time I had not had a test kit for ammonia / nitrate / nitrite. ?I had repeatedly checked the local stores and they were out of stock for the longest time. ?Only recently am I able to test these, and the levels have been okay so far.

I had been doing 25-50% water changes every 3 days or so as the fish was?sick?and I was?unsure?of these?levels.??At one point I?used?one dosing?of?an eco start product?containing live bacteria.??I?have a test kit?now, and the?levels have been?okay, the?only?high?level?has?been alkalinity, which?is as?high as the test kit?shows.??The Ph may be slightly?high, around 8?or?so.??I?have Ph rebalance stuff?but I?am?unsure?of adding anything else?to their tank since I have already used?so many products.??The fancy?goldfish has?not had?very many problems at all, with?the?only?noticable thing being a?very light fading of her?fins?in the 3 "corners"?of?her fancy tail.??This does?not look like the white?on the?other fish,?but?a?more natural beige that appears?more like discoloring of?her orange?fins,?in 3 very small areas.??

Hi Brian,

You say that your readings are okay, but we really need your numbers. There is a box at the top of the page, and if you could answer all the questions that you can, we'd be able to help you much better to diagnose and figure out what is going on in your tank.

PH of 8 is fine for goldies, but please don't use any more meds. They are harsh and can do more harm than good for your fish, especially if you have ANY ammonia or nitrite readings at all.

Post back as soon as you can and let us know your params. We'd be very glad to pitch in and help you figure out what the problem is! :)

Your fish are suffering from new tank syndrome. Water problems. New tanks (less than 2 months) need partial water changes daily not every 3 days. If you click on the links in my sig they will talk you through the nitrogen cycle - the eco-process every tank goes through for the first 2 months to become safe and established. What you are aiming for is creating a nice big colony of good bacteria in your filter media (not the water-a myth) to utilise the ammonia excreted by your fish 24/7. This takes at least 2 months and most fish deaths occur during this period= new tank syndrome. All these symptoms are typical.

I should do an immediate 80% water change, temp and pH matched. And dont worry about high pH - an alkaline pH is good for cycling.
