A lot of times, this can be the result of high ammonia levels. Goldfish produce waste and it can build up to toxic levels. If you don’t change the water, the goldfish can die. I would buy an inexpensive ammonia test kit and see what levels your tank is at.
The problem with a vase is that it usually doesn’t have a large surface area where the water and air meet. Goldfish need a well oxygenated tank. A larger surface area, cool water in the low 70s, live aquatic plants, and a filter will all add more oxygen to the water.
Do a water change, and then look at this post on fin rot. You should probably buy a broad spectrum antibacterial medication. Yo might also buy an ammonia test kit and also one on ph and nitrates.
I have a 3 year old goldfish that i bought at walmart. For the last 5 days he has been curled up like a C. he still eats but I just noticed that his tail fin seems to be deteriorating. What do i do?
We put are goldfish in a vase but he still goes up above the water and breathes why? and also he is like 3 1/2 inches long is there any fish nets big enough for my little Bentley THANKS!!
I was wondering if anyone knew what may have happened to my daughters goldfish? She was what appeared to be perfectly fine when we went to bed swimming eating playing with the other one and by morning she was floating at the top. I’m at a loss on this and my little girl is heartbroken. Any ideas would be appreciated. Thank you
It’s hard to tell but what I recommend is doing a water change and also get into the habit of testing your water for ammonia, ph and nitrates. Poor water quality can lead to symptoms like this. It could also be a swim bladder issues. It could be either hereditary or a digestive issue. See this post on swim bladder problems.
I have a small feeder goldfish , he swims, looks like he breathing kinda hard,, he will swim and then when he stops he goes onto his side,,what’s wrong is he dying,, he came from a pond
