Goldfish can actually tolerate salt water much better then most tropical fish. Quarantine for them they usually sit at a 0.1-0.3% salt solution, and dips are 3% (30 teaspoons per gallon) and when I did the dips on my guys daily, the more often I did them, the more they got used to them and swam around in their salt water like nothing was wrong. Probably explains why the goldfish in that video are the most active fish in that tank. Its gotta be closer to brackish Im thinking... So im leaning more towards what Marie said..
