Yes cycling a tank with make them listless and less active, plus they might not make it as they have to go through the ammonia and nitrite process which can take alot out of the hardy fish.
Even causing the immune system to shut down and desease set in.
I would add two teaspoons of salt to the tank to help the gills.
Take some water from the tank add the salt, stir till it's disolved then add to the tank.
