Per a recent discussion-

I was never planning on posting this here, but during a tank upgrade I utilized an old 10 gallon for short term (less than an hour) for my fish. This is what a healthy 3-year-old goldfish looks like in a 10 gallon tank.

Questions Why do they like spending all their time in here? I thought they’d just pop up for a second, but they’ve basically moved in.

honestly i don't think he's gonna make it, but my dad has hope😂 (swim bladder disease so he's been swimming upside down a lot). i don't know if the face mask is safe to put in the water so any alternative solutions would be great.

I’ve been taking care of this goldfish for the past few months and I realized his appetite has been very unusual.

Is there an explanation behind this? Im starting to get concerned and I feel like if this continues to happen I’m gonna have to take him to the vet to get him checked up on.

Chonker Swim bladder harness!

4.8k Upvotes

My poor 5-year old chonk has been having swim bladder issues for over a month, and despite trying everything (starving for a few days a a time and then feeding only green peas, boiled greens, even minced garlic, and keeping the water parameters a good as possible, etc.), nothing has helped. It looks like this is a genetic issue/malformation.

I decided to make him a harness like I’ve seen online and this is my first experiment. It is nice to see him finally be able to swim around, even with this funny looking contraption, and it thought I should share my (for now) success!

Feel free to ask me questions! The whole thing is made out of air pump tubing and connectors for aquarium, some steel bbs and cork with some plastic string. I had to shave the cork slowly to make him as neutrally buoyant as possible. I’ll keep experimenting to see if i find a better design.

Fish Pics 21 y/o goldfish

4.3k Upvotes

Hi everyone, I have a 21 year-old goldfish that I’ve had since I was a child. He was recently transported from my childhood home in Illinois to my home here in Florida in December. During his travel, he sustained puffy/hazy eyes due to GBD and I have been trying to reverse that even with the help of the vet. He is also stunted in growth as I had not known the importance of the size of the tank as a child so he does have some swim bladder problems but otherwise loves to swim happily in the mornings and has a hearty appetite.

In the last 5 months I have noticed he looks different and he almost looks fuller but I am not sure if it’s health reasons or because he has been fed a proper diet of sinking pellets and repashy instead of flakes that he had the last 20 years. I want to know if his scales look normal as I feel like they’re more shiny and I’m not sure if they’re sticking up or shinier.

For context, I have tried to cycle his tank twice since his move and both times the cycle crashed in the last phase, even with normal GH, KH & PH. So right now the levels are 0 across the board with a PH of 7.4 and temp of 71 degrees F.

We did a Baytril soak for a week for 8 hours a day in February after the vet prescribe it and then since then have tried kanaplex in the tank and metroplex in food when I suspect and bloating. Yesterday night he had a long twisted poop so I fed him a pee and I am hoping there is no bacterial infection but want to start a round of kanaplex tonight after trying it about 2-3 weeks ago when I suspected bloating.

I have read many helpful posts on here so I am hoping anyone help us understand what’s going and maybe give some advice? I want to give my little friend a great chance at many more years of life as he is my childhood pet and is still so chipper at his age.

They had a whole massive tank just for their goldfish and koi (not to mention some very neat handwriting lol). Awesome to see!

I found this little bowl at a thrift store and had the idea to decorate it like a Goldie bowl and put it in their tank. They're so silly.

They have been in that position for a while. Is this normal goldfish behaviour? Checked water and everything, they seem slower than normal. Any idea please or am I just overthinking 🤔. Thankxx

I just got the guy almost 2 weeks ago, he was primarily black, not hers turning gold. Is this normal?
