Fish tanks

I don’t see the fish tanks anymore. Are they still around? Usually, the fish tank was long, sometimes dividing the room in two. There was the fake seaweed, the tiny pink stones on the bottom. The bubbles snaking up the side of the glass. An array of tiny fish swimming around. Usually with one or two big fish. Sometimes one started eating the others. Some fish floated to the top to be scooped up. The residents soon let you know if about the floaters. They could watch forever. So much better than TV and shows they couldn’t follow. What happened to the fish tanks?
