Enjoyed bringing my son here as there is not many things to do with a 1yr old in Vegas.
It's a small shark aquarium but have a lot of different fish and shark species and huge tanks ! They also have a "petting" area with stingrays which was pretty cool. Kelly fish tanks and lion fish tanks too !
Around the aquarium, there are information boards of fish which was fun to read and learn little fun facts about what you were seeing.
Would recommend going if you have children and need something to do.
