Answer 3

That depends on the fish.  Usually, a high protein diet is helpful, but for some, it won't matter that much.  Many need a temperature or pH stimulation (either lowering or raising the temperature or pH), and many will just do it on their own if they're healthy.  A specific method would require you to tell us the specific fish.
