Hello! I am really worried about my large goldfish, Monster, who is suddenly very ill.
Monster is about 11in long and probably about 8-9 years old (he was a "gift" from a customer back when I still worked at an LFS, so I don't know for sure - he started as a feeder fish and just never got eaten!). He lives in a 60 gallon tank (w/ 10 gallon sump filter) with a large plecostomus (~16" - I realize that this tank is kind of too small for him, but it was a temporary situation. This pleco was also a "gift" and he will be moving into a 90 gallon tank in the next few days) five other goldfish who, though fairly large, are all noticeably smaller than him. This tank has been established for about a year and a half with the only change being the addition of the pleco a few months ago. I just did a water change on Tuesday, and have not tested the parameters since. I will update this post with that information soon, but I am so worried and think this is so urgent that I wanted to get this up ASAP.
As of yesterday morning, Monster seemed okay except his lips have been red and puffy for about a week. I thought that he must've "kissed" the plecostomus, so I've been keeping an eye on them and adding stress coat (actually Stress Guard by Seachem) to the water to encourage healing. His lips did not seem to be getting worse and in fact seemed a little bit better though still red and puffy. They were not hindering his ability to eat or breath, and other than his lips he looked and was behaving normally.
This morning I went downstairs to feed my fish and Monster looks absolutely awful. His lips have turned white, his body is patchy and turning white, all of his fins look rotted (the "veins" in them still stand up but they look torn in between), and he is floating around somewhat vertically without much care for where he is...he seems weak and very, very sick. I have tried to take some pictures but unfortunately they don't accurately show what he looks like. I've included them anyway to give you some idea, but they're not very accurate (please note that his eyes are fine; they only look weird in some of the pictures due to the reflection of the light that I was shining in the tank to be able to take the pictures). All of the other fish in the tank seem 100% normal.
The only tank I have available right now to use as a quarantine tank is a 10 gallon which seems too small for him to be in even temporarily, but I am willing to put him there if you all think it would be beneficial.
Please help me. I really love this fish and I have never seen this before...I do not know what to do. The closest fish vet is 40 minutes from me and it is -25° F with windchill outside right now so I am not sure Monster could handle the stress of the trip.
Thank you so much!!

Yes, I use Seachem Prime as my water conditioner (and have for two years, including the life of this tank). I agree that it sort of seems that way, but then I don't understand why all of the other fish appear to be doing perfectly well.
 
I'm going with (and my second guess will probably be overruled here) either:

1. Serious ammonia burns. Are the other fish showing some of the same discoloration or lethargy?

2. Some type of bacterial infection...which if I was treating for it would be columnaris but it doesn't QUITE look to be that...but the puffy lips is what made me think of it.

I would do a 50% water change. Move that fish into a hospital tank asap and treat with salt and meth. Blue.
If that doesn't show any decent change, then I would switch to a cocktail of Kanaplex and Furan-2. Add some SeaChem Prime to the main tank for now as well just in case its ammonia burn, as that will at least help nulify some of it.

I'm thinking moreso ammonia burn as you added a huge messy fish to a tank with 6 messy fish and your bio filter couldnt handle the rapid rise.
I'd add a small amount of salt and Prime to the main tank asap.
 
As I mentioned, no other fish are showing any signs of illness. Also, the pleco (if that is what you mean by "added a huge messy fish") has been in that tank for several months now, and there have been no problems. With water changes every 2-3 weeks, ammonia levels have never been above 0.25 (usually they are 0) and nitrite is always 0. Nitrate is usually about 30ppm. So I do not think that is what caused it.
As I said in my original post, the only free tank I have is 10 gallons. This seems too small for Monster, even temporarily. Do you think it would be okay to use as a hospital tank?
The current tank has salt in it (always does). I have a malachite green based medicine, which I know is very similar to methylene blue. Would that be okay to use? How long should I wait to see improvement before switching to the antibiotics?
 
the pleco is what I meant by a big messy fish, yes.

If you don't think its an ammonia issue then yes a 10 gal tank will be alright for the fish for a few days.

MG is similar to MB in a few ways though in my experience far harsher on fish in the long run. I would pick up some meth. blue if possible. MB has the added plus side of helping the fish to breathe better as well.

The MB dip I've used was 2 teaspoons per 5 gallons with 2 tablespoons of salt per 5 gallons.


If that malachite green has a dip recipe on the bottle then follow that as that is what you have on hand. I would try that for now. I wouldn't wait at all and go get the meds now. The dip may or may not work depending on what the actual problem is. If it is indeed bacterial then you have to narrow it down to what meds show any improvement. Some meds will work on gram positive bacteria, and some on gram negative.
 
It does have a dip recipe. Should I add the dip recipe to the hospital tank? He is now in a 10 gallon tank that has been running with no other fish in it for several weeks. It has an Aqueon Quietflow 10 (no carbon for now). I am trying to get my extra filter (another Quietflow 10) to work so he will have two.
 
I would. Also, get a test done on the main tank and post the results please. That will help too. You did state that you get .25 ammonia from time to time and that shouldn't be happening.

A dip is meant to be short term, so if you add it then make sure he doesn't stay in for more than a half hour or however the long the bottle says that particular dip should be done for. Add some salt to the hospital tank as well.

Hows he acting currently? extremely lethargic? is he swimming upright?
 
As soon as he moved into the hospital, he seemed almost to calm down. Now he is mostly staying in a corner on the bottom with his head against the wall. He looks sort of depressed, actually. But he's no longer swimming around vertically which seems good...
**Edit: I forgot to mention that I also put a small airstone in the hospital tank.
**Edit 2: I forgot that my friend has my water parameter test kit...I will have to get it from him.

ehh...well both behaviors don't sound great...just keep an eye on him...best you can do right now.

airstone is a plus. good job on that.

yes, get that test kit. I, along with anyone else who chimes in, will need your water parameters. They effect what types of medication you can use and also if you even need medication because something could be very out of line with that. Also, just because only one fish is showing visible signs of sickness does not mean the other fish aren't affected. I've had ammonia spikes kill fish in a tank while the tankmates continue on like nothing happened.
