HoloLens Aquarium is a game that gives players the chance to create their very own aquarium. In addition to choosing to decorate the aquarium in a large number of different ways and then fill it with the fish of their choice, players can also take a special fish trivia quiz to test their knowledge. However, once players have created the perfect aquarium, there is very little for them to do except for sit and look at it, which is likely to become boring before long.
