AbsolutAngel04 suggested I reach out to you for a little help with a goldfish.
A year ago some friends bought me 3 wal-mart goldfish and a small 1gallon tank. 2 died within a few weeks but 1 of them is still alive and swimming. Recently I decided to move him into a larger tank, 20gallon. I got the tank set up and running and left it for a week. Then I moved my goldfish into the new tank and for about two weeks now Goldie just seems to enjoy camping at the bottom. When he does swim its very fast and erratic. I'm pretty sure he crashed into one of the decor pieces since he is now missing 4 scales. He prefers to "float" around the tank. Whenever I enter the room or flip a light on he darts back to his hiding corners. He still eats but won't venture too far for food. His poop is long, clear and stringy. Every other day I am doing a
pwc of about 5-6 gallon, adding the chemicals to make the room temp water safe for fish.
Thoughts?
