Goldfish Euthanasia??

HI everyone.
I have had a blackmoor goldfish for about 9 months, and I assume he’s a little over a year old. Ever since maybe a month or two ago, I started to notice he’d occasionally swim upside down. I noticed it could be swim bladders disease, but it didn’t seem as bad as other cases i’d seen on google and forums, so I decided to not feed him for a day or two and switched him to different food incase that had something to do with it. His condition only got worse, but I knew it probably didn’t have to do with his feeding, so I just left him be. About a couple weeks ago, he realized he had a problem swimming down, and that he spent the majority of the day in a corner with the base of his tail floating up, mind you he was always right side up. Then, maybe last week, he began to flip more often, and eventually only stayed bottom side up, in which case I put him in a quarantine tank all by himself. It’s recently gotten so bad where he’s never right side up, and his body contorts so one side of him faces up and he looks like he could even be dead. I’m afraid at this point he may not be able to find his food and eat or even not be able to get to the filter to get water poured on his stomach.

I don’t want him to be in pain and suffer, but at the same time I don’t want to have to euthanize a fish that has a chance to get back to normal. If I did have to euthanize him i’d go for the clover oil method which seems to not cause pain, but I want to have done everything I could to help him go back to normal. Any advice would be greatly appreciated

 

Blanched peas, more frequent water changes, and antibacterial treatments are all ways to treat both bloating and swim bladder. Also pictures and such are helpful.

the pea method was the last thing I was going to try, i’ve been doing a 30-50% water change every week he’s been in his new tank. Do you have any recommended anti-bac treatments?

 

Honestly, sometimes it's not a feeding issue (or at least not the main issue). Mainly, swim bladder problems are a result of fancy goldfish and their deformities. Many will have this chronic problem that will never go away. Some make fish "wheelchairs," but, really, what's the point?

 

Aspirating Floating Goldfish. Severe Swim Bladder Disease.

 

If you are having trouble with high nitrates you will see problems with swim bladder disease.
I drain basically all of the water out of my goldfish tanks every week to give them fresh water. If the nitrates go above 40 I will notice a change in the fish. They're more prone to bottom sitting and hovering. Changing water can revive them. Try doing huge water changes every day and that may be enough. If not, I have found excellent advice for medical treatment on koko's goldfish forum in the past when I adopted sick fish that had swim bladder issues. There will be some fish that do have deformities due to their variety, and some of what I have read indicates that sometimes an infection can play a part, but water quality is always a huge contributor to goldfish issues. Try clean water first. Good luck!
