Is this Ich?

All my goldfish are acting normal but I can’t tell if these white spots on my fantail are ich or just a pattern in her tail. Her colors have changed a lot since I got her but I want to double check. I tested the water and added some aquarium salt for good measure but everything seems fine. Tank is a 45 gallon with 3 fancies.

Goldfish type?

Hi all, I’ve had this goldfish for about four years now and I was curious if there was such a thing as an albino goldfish! The whole time I’ve had him he’s never developed color. Is there something wrong with him? He eats normally and is very active. Although, he’s always had two cloudy eyes so I wonder if he has trouble seeing.

Outdoor pond questions

I am about to invest in a semipermanent pond for 2 common goldfish I have. I found this looking at stock tanks. It’s 106 gallons, reasonable reviews on amazon. Would something like this work? It comes with a liner and a pump.

Otherwise I’m just pulling the trigger on a 300 gallon Rubbermaid. I just like the view windows in this setup.

Getting my goldfish a friend

Hi!!! I got my goldfish just about a year ago today and he is currently living in a 29 gallon tank.

He is a very happy fish, always eating, always swimming around, and sometimes if you put your finger in the tank he will swim up and kiss your finger (he really wants more food).

I keep reading/seeing that goldfish do better and are happier in pairs. My only concern is, he has been alone for a year now and has grown to about 4 inches (I don’t want him to eat a friend).

Would it be beneficial for me to get him a friend? Or should I just leave it be? Thank you in advance.

Salt bath and surface gasping

My comet has been inside for about 5 days now in her hospital tank. I've been giving her Epsom salt bath for the last two days, 15 minutes in the bath and then I move her into a clean dechlorinated tank with an aerator. She has shown signs of improvement since I brought her inside for observation and treatment. She was starting to lift her butt when I pulled her, (I thought she had dropsy but shes not pineconing, she's just bloated) and yesterday I noticed she has definitely leveled out and isn't butt-lifting anymore. I'm wondering what the deal is though because when I move her from her salt bath to her clean tank, she spends the first ten minutes or so doing alot of big gulps and surface gasping. I don't want to stress her out any more than necessary, and the surface gasping concerns me a bit. She does eventually stop, but I'm wondering why she does it. Insight or advice?

What's happening to my Oranda?

At first he was being "lazy", bottom sitting most of the time and only swimming sometimes, mostly for food. But he started bottom sitting more which made me think something was wrong with him. He started bottom sitting slightly on it's side, when he was swimming then stopped he would drift up. These symptoms pointed me to Swimming Bladder Disease so I put him in a 5gal bucket with brand new water and a little bit of epsom salt. I have not fed him for the last day and he still hasn't excreted. His condition seems to be getting worse, his natural black spots seem to spread on his tail and his skin seems to be turning a little pink.

What could this be? How should I proceed?

self injury?

my goldfish has this spot on his face that i think is getting bigger. the tank has also been treated for anchor worm for 3 months now (just on a prevention because they all had it, now it’s gone or one or two will show every now and then) and i was wondering if this was a self injury or some type of infection. none of my other fish have this injury.

Gravel vacuum heads

Anyone have recommedation on gravel vacuums that actually have serviceable parts? I have a gravel vacuum from Amazon that works well, but getting parts for it is dam near impossible unless I just buy a whole new unit. The biggest thing i am looking for is the head attachment that goes on. I am looking for an attachment where it has a flared out end. Any ideas where you can get these attachments without just buying a new pump?

Tankmates

Hello folks. I'm still new to goldfishing , as we unexpectedly won a common at the fair, picked up a 10 gallon tank, a 25 gallon filter, some gravel, a teeasure chest bubbler and a live plant among the plastic plants. We are looking for a 25 gallon to upgrade her here shortly but in the meantime, I have 2 questions

#1 i know that the sucker fish are a bad idea as they get huge but is there some sort of other cleaner type tankmate I can get her? Obviously not going to make whatever it is LIVE on just tank slime, but just another level of cleaning on top of filter and plants. Someone said snails but that's another world for me.

#2 are there any other fish that ARE ok to share a 25ish gallon tank with a goldfish? Preferably something that is and stays small.

Just curious. Thanks!

"New" Goldfish Keeper Questions

Tropical fish hobbyist (with 4 tanks running atm) looking to setup his first goldfish tank; I've got a 4', 55 gallon I will be housing them in. I've kept fish for many years so I will be ensuring parameters are correct and the tank is cycled before purchasing any goldies!

But I had a few questions I'd like some input on!:

  • Differently-sized goldfish? I'll be keeping the short-body, fancies in this tank. I was wondering what the rule of thumb is for keeping different sized individuals together is? Like would a 2.5" be ok with a 4.5 or even 5.5"?
  • How many fancies would you personally stock in a 55G? I've seen several sources say one pair in a 40 gallon; but I have gotten mixed reception on "10 gallons per extra fish, 20 gallons per extra fish, etc". I will be keeping at least two, but seeing how many cute variations there are I would love to have a 3rd (for this tank) if I could accommodate it!
  • Where do you like to get your goldies from? I heard Goldfish Island was good but they are closed; and I've liked the selection I've seen on King Koi & Goldfish as well. (I do also have 3 local chain stores and one "mom & pop" LFS nearby that may carry them as well)
  • Controversial question, but I'd like honest answers from people who actively keep goldfish: Tank mates? I'd love to have snails, obviously large enough to not be eaten, as I can't see there being compatibility issues. I've seen some people suggest White Clouds and other smaller Dither fish species. (I am totally fine with a goldfish-only tank, but would be open to expanding it to other fish if its possible)
