i really don't know what GH and KH should be but if it maxed out your test. i would say its to high. try a 35% or so water change but test the water before you put it in to see what that is.

flashing is a fishes way of scratching themselves. the occasional once or twice is not naccessarily a cause for concern, but more often than that or multiple fish flashing very well could be...parasites under the scales is a problem and one that can spread and lead to serious health issues.
