Hey everyone. I have a tank about 170 or 200 gallon with a community of fish. over a week ago the flowerhorn in this tank had a real bad rash on the side of him and lifted up a whole couple rows of his scales and died. Right now there are other fishes in the tank that are appearing rashes on them and im not sure what i can do. the tank water has been changed.. Have not been able to add any salt in there about to go get some salt after i post this cause i ran out. thinking about pouring a container of salt in the tank help them out a lil. any advise ??? anything would help thanks..
