In 2010, Nordsøen Oceanarium completely rebuilt their old entrance building, making the building much more open, reducing the 20+ medium-sized fish tanks to four big fish tanks, and revamping the fishery exhibitions so that they have become much more interactive and kiddie-friendly. While I'm not a huge fan of the loss of tanks and species, nor of the exhibits being dumbed down, I'll admit that the new building and the the new fish tanks do look nice.
"Molen Hirtshals" is one of the four new big tanks and represents the underwater life by a pier at the port of Hirtshals, the town in which Nordsøen Oceanarium is located.
The species are: Whiting, dab, goldsinny, thick-lipped mullet, cuckoo wrasse, European eel, striped red mullet, eelpout, brown trout, Atlantic salmon, Atlantic cod, John Dory, red gurnard, saithe, shorthorn sculpin, and common dragonet.
