For some people who wonder why they do not acclimate the fish with water drip method or something similar. That's why: During transit your fish is excreting ammonia and CO2. The CO2 built up within the shipping water helps to keep the pH of the water low. In water with a lower pH, ammonia is much less toxic than the same amount of ammonia would be in a high pH environment. As soon as you open the shipping bag, CO2 begins escaping into the air, and the pH of the shipping water can quickly rise. As the pH rises, it can cause pH shock and also causes the ammonia built up in the shipping bag to become exponentially more toxic. If you open the shipping bag and attempt to gradually acclimate your new fish to your aquarium water by pouring some aquarium water into the shipping bag over a period of time, you are potentially exposing your new fish to irreparable damage. Simply float the bag for 10 minutes to match the temperature, open the bag and quickly transfer your new fish into your aquarium with your hands, and discard the shipping water. (source: solid gold aquatics) And in this case, they don't need to adjust the fish to the water temperature because they heat the room and not the aquariums, and with the boxes standing there for while, they already have the right temperature.

in sintesi: metti i sacchetti nell'acqua dell'acquario per portarli a temperatura uguale, tienili per almeno 30 minuti così sei sicuro. tieni i sacchetti chiusi per non far uscire/entrare aria.
quando la temperatura dei saccheti è uguale a quella dell'acquario aprine uno a uno e metti nell'acquario solo il pesce, non l'acqua dei sacchetti.
