We need a marine exhibit like this (Video)

Any way to get high quality fish tanks in game I am for.

I had something that incorporated your wish. See what you think.

Agreed. I would love if maybe somehow EA can create a new feature called “Pool effect animations” of different species of fishes in the game and added it anywhere inside the water of the pool (from above water to underwater) to use it to create your own marine exhibit or Aquarium to create inside the rooms & maybe using new pool tool feature to make giant glass tanks to make transparent wall as tanks in residential & community lots. Just like they did with the pond effect animations except you can’t move it underwater.
