I also find some of the fishes in this aquarium is sick. A stingray has a rotten side. Some of the fishes that doesn't look lively.
Now, I am comparing apple to orange here. I went to the aquarium in Okinawa this summer, and the price for the ticket was cheap. I think it was about $20 CDN. It has the 2nd largest aquarium glass or something in the world (I am actually not sure, but someone told me after I came back to Canada). The place is huge, and there are a lot of variety of fishes and sea animals there to see. Also there is the deep sea section which I find it quite fascinating.
Here are the pictures for the Ripley's Aquarium in Toronto...
