This video is old but its amazing how low or high they can make a fishs salinity level . However with the saltwater fish they could possibly explode with no salt to excrete I have also seen a damsel in a fresh water tank that lived for a month befor a chiclid ate it if they could fully switch clowns they would make so much money. But I don't like the look of them together thought it was just interesting to share.Check out this video on YouTube:
