1 of my Goldfish i think has swimbladder he dont seem to be able to stay up straight. i checked on internet for some advise i put him in his own bowl with shallow water and added salt he seemed to perk up and also feed him food that sinks which he will now swim for but then just lays back down but now he has started to get black marks on his body he has been like this now for nearly 2 weeks all my other fish are ok they are not fancy fish any ideas what i should do now

What do you mean you put him in his own "bowl"? I'm hoping not literally a small fish bowl with no filtration.

It's good that he's still got an appetite. Is your Goldfish bloated? How do the scales appear, are they raised? This would indicate a serious problem.

Where are the black spots located? Has he ever suffered from injury or fin rot prior to this? A picture would really help.

I'm also curious as to what kind of tank you keep your Goldfish in and how often you perform water changes.
