Looks like a really cool collection of fish. I can see Rudd, European perch, Siberian sturgeon, Russian sturgeon and Common carp, but I don't recognize the fish in bottom left or top left.
@Mr Gharial hahah yeah, the Baltic Sea has a really low salinity on the Finnish coast, so both it and this tank (which was 10 meters in diameter and 7 meters deep) have lots of freshwater fish
The species in this tank were: rudd, roach, trout, lake trout, eel, rainbow trout, pikeperch, perch, Russian sturgeon, and Siberian surgeon.
