I have visited in here a few times but most of the time I'm in the Ponds and Aquatic Plants forum. I have a question that concerns a goldfish that my wife has in an aquarium. It won't or can't swim to the bottom and when it does stop swimming, it floats right up to the top, right side up and level. I'm sure that it has some sort of swim bladder disorder but what can be done to correct it? All help would be appreciated.

Thanks,

Scott
