What are your parameters? We need to know the exact numbers, not just “fine” or “safe”.
Ammonia: 0
Nitrite: 0
Nitrate: 0
pH: it's pretty high around 8.4 and stays constant in the aquarium and untreated from the tap when I did an overnight test
not surprised about them being all zero as I have been doing daily 25% water changes for ich treatment with rid ich

Illness & Symptoms
How long have you had this fish? Aug 1st 2021
How long ago did you first notice these symptoms? first noted ich bumps around Nov 5th got medicine and started treating around Nov 10th. Now today Nov 17th noticed one fish pineconing barely, and 4 with red streaks in fins that were not there a few days ago.
In a few words, can you explain the symptoms?. ich bumps and red streaks on one fish, one fish barely pineconing, 4 fish with red streaks in fins, one I think the medication aggravated my fish with a history of swim bladder issue which I just got to go away, and these are all separate fish only one has no signs of anything
Have you started any treatment for the illness? yes started ich treatment with rid ich on Nov 10
Was your fish physically ill or injured upon purchase? Had big case of ich I treated and thought I got it but now I'm not sure if this is the same ich or if they caught it again.. other than that when I got them the only symptoms were white bumps all were very active and eating
How has its behavior and appearance changed, if at all?
no behavior changes only physical like ich bumps, pineconing, and red streaks

Explain your emergency situation in detail.
(Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
so I already wrote all this but I'll restate. I've been treating for ich for 7 days with daily 25% WC, haven't treated today because I noticed other symptoms: red streaks in multiple fish very minimal in most of them early onset I think and one dark one on one fish, pineconing just a little in another, and my fish with a history of swim bladder is having very minor issues. I googled and could not find any info on fish getting sick after ich treatment. I was thinking maybe the rid ich weakened the immune system and either they had an existing illness I didn't spot or the contracted one from the stress. I have attached pics of the ich which originally started on this fish's fins but is now only on its head, red streaks, pineconing, and fish with swim bladder issues. Any help will be greatly appreciated.
To add I've treated what I thought was hemorrhagic septicemia (red streaks) in another group of goldfish maybe 2 years ago. They came with it when I bought them and I was only able to save one and he made a full recovery. I forgot what I used but it was like a yellow powder from petco/petsmart.

 

are you talking about the white bumps on the 3rd photo on the wen (head) ? those are usually new wen growth. ich will be all over the fish. i don't see any ich in any of the photos.

what were the water parameters before all this started?

what was your water change schedule before all this?

pineconing is usually an internal infection.

sbd could be high nitrates, or gas from food or gulping at the surface (floating foods), or internal infection. try fasting and epsom salt baths. then feed peas and green veggies.

also, do you thaw the frozen blood worms in a bowl/cup of tank water before feeding?

 

It started on his tail first I know about the wen growth but that occurred in the past few days. A week ago he had spots all on his tail. Water parameters before not sure bc I stopped testing after it read 0, 0, and a few nitrates for about a month with weekly 25 to 50% WC. The food I feed is sinking pellets and I defrost the bloodworms all the way in a cup before feeding. The one with the swim bladder was under control until I started ich medication. How should I treat the internal infection?

 

there's a variety of antibacterial meds available, like erythromycin, kanaplex, furan 2, etc

Should I treat him separately or do the others have it from being in the same tank for so long?

 

Seems like a serious water quality issue...crashed cycle or chronic exposure to high nitrates or something.... I would try to accomplish a 90% water change, which can be done with 3-4 ~50% water changes. For a 120g that's a lot of work and a lot of water but that's the nature of having larger tanks unfortunately. The water level also seems very low...are you normally filling the tank to the top with water?

I dont understand how it's a water quality issue? It was normal with a few nitrates and then because of ich treatment it went to zero due to daily WC for ich treatment so they were never exposed to high anything especially for the past week of daily WC. It was low because I was in the middle of a WC. Also I tested everything before that WC and it was all 0

Water quality is not just the nitrogen cycle. Any food, poop, waste can reduce water quality. That's one possibility.... Others could be KH was depleted, changes in the city's tap water, or something else entirely

 

I'll clean it out again to be safe and try to save my fish but I honestly don't think that's an issue I've been vacuuming and doing WC daily for past week following rid ich instructions so no poop, food, or waste has been in there longer than 24 hrs. But like I said to be safe I'm trying anything I don't want to lose my fish. I tested water recently because I had to fill an outdoor pond and everything has been the same for past year and all my other tanks are doing good so it's not a city tap water issue either or I think I would be seeing problems with my other fish tanks.

 

Does your city have tap water reports? 8.4 pH is very high...Im really curious what's in the water....

Here is the report I just looked up

 

Oh yeah Texas College Station, I've seen this water report on here before.....Definitely some crazy numbers, very high pH and KH.....but almost no calcium, and magnesium not even detected...? Not sure if you can keep fish in them for the long term.... GH needs to be supplemented somehow.

How can I do that? And how does it work with WC? I have the test kit for GH so I'll be able to monitor it

Unfortunately WC is not going to do much. Usually most tap water in the US has some GH so just WC will replenish it. In your case there's essentially nothing... Your LFS should have GH boosters ie Seachem Equilibrium

A high quality diet will also be important...since you have goldfish try feeding boiled peas, spinach, kale and other vegetables

Do you know what levels I should shoot for GH wise with the equilibrium and should I start monitoring KH and others as well?

Hmm just try to go for 4-6 dGH. Start with the minimum amount the instructions provide, and then over time with each weekly water change you can add a bit more until 6 dGH

 

Ok thank you so much!

 

No problem and dont worry about KH your watrr has a ton of them
