sick freshwater oranda

Question
i have a brown and silver oranda named coco. she tries to swim down on the bottem of the tank like my other fish but she floats back up to the top. i don't know what to do, can you help?  

Answer
Sounds like the beginning of swim bladder disease. There is medication for it. Swim bladder disease interferes with their ability to swim normally. Your local fish retailer should sell the medication you would need. Best of luck and happy fish keeping.
