Looking for something to do with the family on the Fourth of July? The Greater Cleveland Aquarium is open. “There won’t be any fireworks, but the flashlight fish twinkle, the poison dart frogs offer a brilliant pop of color and you can look up for pretty spectacular view of sandtiger sharks gliding overhead,” says Aquarium GM Tami Brown. Free parking for everyone. Free entry for military and first responders with presentation of appropriate ID. Accompanying family members are eligible for discounted admission.
