The fish in my aquarium keep dying mysteriously.

There is no sign of ich, velvet but they do appear to get some kind of lesions on the skin.

They can be fine for weeks and suddenly lost appetite and dies without gasping and shows no white spots. Also the fish doesn't die together, they dies one by one.

I have two tanks and the other has no such problem.

I plan to remove all remaining fish and my question is if I run the tank in fresh water for a couple weeks, would that get rid of all possible disease?

All water parameter is excellent before or after the hyposalinity. (only 7 fish left from 20 in 1000 GL of water)

The tank is currently running hyposalinity at 1.009.

What should I do with the rest of the 7 fish?
What should I treat them with?
