We love aquariums, and being new to the area, we were happy to see there was an aquarium in Cleveland. You only need about an hour to fully see everything. The majority of the displays look very clean and true to the fishes natural environment. The shark display is very nice and we were even there for a feeding which was pretty cool. There is an octopus which was interesting as it had recently laid eggs.
All in all, a nice aquarium, but not sure a $20 admission fee is worth it. I have paid that much for aquariums with much bigger and better displays and I could spend a longer time enjoying them.
