Open Bottom Aquarium

no it gets trapped in there. Once the tank is displaced with water it will stay there unless something can take its place. Being that the tank is a sealed chamber it stays suspended in the tank. Its the same science behind the old upside down cup in the kitchen sink. Fill the sink and turn a cup sideways till it is full of water. Then turn it upside down and pull the cup. Presto the water is suspended in the glass. Same idea here.
