                        Hi, I don't know about the fish-help, but I do know that SALT WATER is a great cure.  Spend as much time as you can swimming in the ocean, or visit the DEAD SEA.  Any body of water which is full of salt - is supposed to be great for psoriasis.   Unfortunately, I can't afford to travel, I hope you can.
