Shanghai Aqurium
I’ve been to 2 of note. The one in Sydney, just behind the harborfront, and this one.
Both have large pools, and as you’d expect, fish.
The fish swim around you in many tunnel things. Sometimes they do nothing.
The signs are in English, as well as Chinese.
The Chinese are well behaved, there are no Chinese trying to catch the fish or spitting in the pools.
I spent a couple of hours in here. It’s easy to find. Right next to the Oriental Pearl Tower.
