Is there such thing as a SG Shock?

I see.
Just to make sure here. So you mean when I get a new fish I can really just. more or less, dump it right into a QT with a SG of around 1.010-1.013, which is pretty much hyposlainity? But when I move it to the display the process of going to higher SG has to be slow?
I read about going down is okay but going up is troublesome because it causes dehydration. Is that why?
