Hi there, I know you are all going to cringe when you read this, because I had no idea what all was needed for a goldfish. This fish was given to us by my nephew (who is 3) when he moved out of state, so I just kept it as they had it. I will answer all the applicable questions from the sticky, although most of them do not apply to how this fish is being kept-I had no idea I needed filters and testing equipment.
So here is the situation, which I think is pretty grim. The fish, I believe, is a "fancy goldfish". It is pretty small, about 3" in length. It is very ill. About a week ago I noticed that it had some light brown patches on it, mostly on the head and upper body. I cannot see anything else unusual about the scales, no specks, scales look ok otherwise, nothing hanging off of it. I looked at all the goldfish disease pictures on this site and none of them look like what is on my goldfish? The brown spots seem to be the least of his problems though. Here's a timeline:
A few weeks ago he started floating sideways in the tank, I changed the water (75%) and that seemed to help although he still floated sideways sometimes. A few days later I found him lying on the bottom of the tank, virtually motionless but still breathing. I did a 25% water change daily for the next few days and then he seemed fine, eating and swimming normally. About a week later hew started the sideways swimming again and then developed the brown spots I mentioned above. Since then he has become much worse and eaither floats completely upside down or on his side. It seems like he is not using his left side fins at all either. He kind of floats up and down in the tank (upside down or on his side), seemingly propelled by the bubbles from the aerator. The last two days he has not been eating either. For about a week, when he poops, it often hangs on him for quite awhile, which I have just learned may be a sign of constipation. I want to know if there is anything I can do, or if I should just put him down? I have been changing 50% of the water daily for the last week but until I found this site I didn't know there were other things you could do, and that he probably isn't being kept properly in the first place. I'll answer the applicable questions from the sticky below. Thanks for any help and sorry, i am sure this is appalling to all of you, I wish I had known better! the fish had been living in this tank for over a year and done fine, so when it became my fish I just kept doing the same things, which I am now regretting.
