Js got bro, is he high quality? Also when should I expect wen growth

Hi everyone! This is my child Nugget I’ve had him for about 3 months now (He was 2 months when I got him). He was my first Goldie and I picked him out because I thought his gold/bronze color was beautiful but I’ve since learned that the bronze color is a young goldfish color and that he will change which I’m super excited to see. I was wondering around what age will he start changing color? So far he’s developed a few white and black scales so I’m even more excited to see what color he turns out to be! Apologies for the blurry pics lol I haven’t figured out how to take clear pics of fish yet. (Also ignore the green air stone the power went out so I had to drop an emergency pump in there)

This popped up today, I love this lol guy and am quite worried about it, I’m not an expert in any way so any advice/ explanation as to what it could be would be appreciated.

New Oranda goldfish, was showing signs of illness at the store, initially not diagnosable, but now fully blown fungal disease. In your experience, which anti-fungal medication is the safest and most effective for goldfish?

What is the warmest temperature you guys have had success with keeping fancy goldfish?

I keep seeing this weird foam on my tank. I put in some microlife today and i did a 50 percent water change. I also cleaned out the filter but they keep appearing back on the tank.

My goldfish was in the “i’m being a bully” time out tank. Somehow at some point during the night his oxygen became disconnected. Based off when i woke up and his condition i’d say he did not have an oxygen supply for nine hours or less. He had oxygenated water to start. Anyways. he obviously has hypoxia, but is managing. I’m wondering what i should be looking for, what would show progress etc. I have decided if he clearly has lost cognitive function i will put him down. I want to know how long i should wait before making this choice, and/or what i should look for to determine if this is the right choice.

I'm so excited I've had him for a year and been fighting to get a big enough tank so he can have friends.

exactly 80 days after my original post when i found out my oranda was being bullied and i took it out of its tank, it unfortunately passed.

my oranda had been severely injured while in its previous tank, and i had carelessly not noticed. i took it out immediately and did everything i could, and it started getting better. it's scales and fins were healing wonderfully. it was swimming around and eating its food again.

however, that phase ended a few days ago when my oranda slowly stopped acting like its happy self. it started laying on the bottom of the tank and not eating.

and today, when i came home from my mri, i saw him on his side on the bottom and i just knew he was gone. i lifted him out of the tank with my hand, and he didn't flinch or start flipping or anything.

i'm utterly devastated.

I could sit in front of their tank for hours, and they stare at me as much as I stare at them 😂

(Don't mind the mess, they get messy foods before a water change)

Added 2 new members to my goldfish family. Everyone meet Salt and Pepper! Love how one is spotted and the other is patched. My goldfish family is up to 8 currently.

Why there fins are black brought them today The shop guy said it's normal..🤔

Only this guy has it. Others are fine

I will be on holidays for 4-5 weeks. I have this 1800 Liter tank with 5 goldfish.

Can the fish go without food? Any experience with food blocks?

Otherwise I will try to arrange a neighbour who can feed.
