I've only seen aquariums mentioned briefly in one other post by the user "Dog". I mentioned this idea in Lee's stream and he and a few others thought it would be cool. I'm an aquarium fanatic so having aquarium options as well as your choice of fish and aquascaping would be a huge enjoyment for me and seems like it would add more customization to the apartments. This would be a separate little customizable space that players can make very unique. It would also be cool if the fish could have very simplistic AI so that it isn't just a loop of the same behavior over and over, they may go into a feeding frenzy and/or have random schooling patterns, that sort of thing. Of course you would want to keep them realistic in design though, for instance you wouldn't make a 6" Zebra Danio or make a Kuhli Loach swim slowly in the mid level of the aquarium and be aggressive to other fish or have a saltwater fish in with freshwater fish, etc. etc. I would be happy to help with those details and include images if needed.

Will there be amusement parks? How about zoos? Aquariums or marine parks? It would be nice to take a trip to one of those, and get on the roller coaster, or even sneak out a giraffe from the Zoo and sell it to someone LOL.
