I have a room in my FC House and have an aquarium which I can place, but I am unable to put the trimmings in it, add fish, etc. how do I do this? I get an error saying this item cannot be placed in estate hall, but I am in my personal room. when I got the aquarium and reading posts my Tier 2 aquarium says I can use it in my room. Any help would be great !! Thanks.
