Are fish in tanks/aquariums aware of the fact that they live in an enclosed space?

Probably depends on the fish.  Some groups of fish (e.g. mormyrids, gymnotids, notopterids, gymnachids) have either passive or active electrosensory abilities which allow them to image conductivity of their surroundings in three dimensions; these fishes would be directly aware of how small their habitat actually was.
