Decocean Aquariums gets fish from Tropical Marine Centre in England (TMC). Carsten - owner of Decocean Aquarium - has himself been to England to see TMC facilities, and was very impressed by the treatment the fish get at TMC. TMC have a very straightforward and extensive quarantine system where the fish absolutely do not get any kind of stress. The fish are not sent to Denmark until they are completely fresh and de-stressed. TMC quarantine is 3 to 4 weeks.
