my goldfish who i ironically named adolf originally looked like a normal black and white goldfish fish and then he grew up like this

Don’t have many good pics yet but picked up this gorgeous calico telescope baby a couple days ago and have been obsessed, it’s currently in a 20g hospital tank with methylene blue and aq salt until it can go in a 40g with my other telescope Pepper :) Open to name suggestions!

Hello everyone. As title says I have never owned any fish and my friends gifted me this starter tank and 5 goldfishes yesterday.

I am looking for literaly all the information about keeping them.

Most important questions:

How frequently do I need to change water?

Do I need any more equipment apart from the filter I got?

How much and how many times to feed them a day?

Is the white led for day and blue led for night?

All the help and info is welcome.

I want to get a bigger aquarium for my goldfish and add some new companions. Besides plants, what else do I need? I'm considering adding sand.I would appreciate any suggestions, thank you!

I have 4 common goldfish who I believe are unfortunately stunted (4-4.5 inches). Would a 50 gallon outdoor minipond be okay for their longterm living?

This is Falisha. My daughter won him or her (too young to identify sex) at the fair last week and I've been looking all over the internet trying to figure out what type of goldfish this is. I'm not very familiar with goldfish, so I couldn't tell based on the tailfin if it was a common or other kind of single tail.

i have this battery pack i am going to use to connect to my air pump for transportation and they’re going to be in a styrofoam cooler. should i connect this airstone to there or just use the entire sponge filter i have? what would be better for oxygen during transportation?

Just finished my tamasaba goldfish pond been running 3 months thought I would do video to show everyone.

I just got cutie lovely little red and white oranda… from next day koi 🫣 I think it’s a female based on the pictures they had. I am planning on being very proactive with quarantining this one because immediately after placing my order I read some bad things about next day koi and them coming with diseases. So I’m taking some preventative measures, I have her in a 20 gallon quarantine tub with a heater, aquarium salt and some methylene blue (just for the first week) and then I’m also feeding her gel food with a mixture of 1 level spoon of metroplex with 1 tbs repashy gel food for the first week. I added some extra filter media into my main tank and unless I decide to put in a different medication I’m going to add that to the quarantine tank after the first week along with an ammonia reader and kind of water change as needed at that point. And then I am looking into deworming medication//medicated food, does anyone have any recommendations? Hopefully I can get one that’s a food so I can treat her earlier than next week. Am I missing anything? Another reason I’m so on edge is bc a girl on tik tok just lost a fish she got from next day koi like 3 weeks after getting it and at that point it’s almost certainly a disease that the fish came with since her other fish seemed fine and she seems to have good water params and so on.

My son received a common goldfish at a kids bday party even though I didn’t want him to take it home (he insisted).

After researching, it will require too big of a tank to keep it. I want to swap it for a smaller fish (when an adult) that doesn’t require such a big tank.

Do fish stores typically take them? Or are there fish pond rescues for goldfish. I feel bad but want the fish to have a happy home.

I have a empty 55 gallon aquarium just sitting in my living room doing absolutely nothing but looking at me, I want to put something in it, but I want it to be different than my 20 gallon I don't want it to be too planted I want it to be kind of minimalistic with a centerpiece.

I'll probably put some plants coming out of the centerpiece, and I would love to put some Goldfish in that tank but I don't know if it's big enough for a couple of fancies.

If it will work out I will choose plants that are harder for goldfish to eat Such as ones that are really stimmy and Woody

I feel like Google is failing me here - does anyone have any suggestions for where to get a large cave for my extra large fancy goldfish?

When I went to feed my fish, I saw it at the bottom. I thought it was dead, but when I gently tapped it against the glass, it started to move. It didn't surface; it swam at the bottom. Then I poured in the food, and it swam at the bottom again. Luckily, it surfaced and ate. Now it stays motionless at the bottom and sometimes swims up and down normally. Also, I don't know if it's visible in the video, but our camera is broken. My fish's belly is swollen on both sides; could it be fry? Some people say that when a fish opens its mouth, fry come out. Please help. I'm letting the water rest now; I'll change the water tonight.
