Yep, stressed out. Jumping from one tank to another is rough on the system. Read this about osmotic shock.
Osmotic shock.
Most fish regulate how "wet" their bodies are through active osmosis, this basically means that they have the ability to pump water in or out of their bodies to match their current conditions, most oceans are very similar in levels of salinity, so normally this isn't a problem.
The problem starts when we as keepers neglect to inform ourselves of the chemical composition of our tanks, the salinity, ph and hardness all play important roles, this form of infection usually presents itself if a fish/invert is placed in a bag at a lfs, then carefully transported home, the keeper then opens the bag and dumps the poor fish into the tank, the difference in ph and salinity between the 2 tanks may not be significant, but it usually is enough to make the fish pump out so much internal water (in a attempt to become more salty)that it dies of dehydration( this would happen if your salinity was higher than the lfs) or the opposite if the salinity is lower than the lfs the fish would start to suck in water to become "less salty" and match its environment, this usually causes internal hemmoraging and renal failure resulting in a slow and very painful death.
inverts are especially prone to osmotic shock due the the hard exoskeleton which means that water takes much longer to diffuse inside its body.
what can you do to prevent it??
This is the easy part.. try to match your lfs water parameters if possible, make your tanks salinity, ph and hardness as close to theirs as you can to minimize shock, and always acclimatize well, float a bag with a new fish in for a few hours, adding 10mls or so of tank water to the bag every 10-15mins so the animal/invert/coral slowly becomes used to the new water chemistry, this may take a few hours of hassle, but it reduces almost all chances of shock, and stress induced disease like ich.
Go ahead and get another one to put in the tank with your new one, but acclimate it slowly and properly. Take the time.
