Wow. I haven't been to many aquariums but the exhibits here are amazing. There are also lots of interactive sections for kids. You can touch crab, stingrays and small sharks.
The best exhibits were
-the underwater hall where you feel like you are in the water with the sharks and fish
-the jellyfish
-the seadragons (u probably haven't seen one before)
The downside is the admission price. It's $30 CDN to get in.
