At the same time though it also gives their brain a slight break – people without heavy training cannot maintain solid focus for eight hours straight and so one way or another they will need to take breaks from their work. By having custom aquariums in the room you can provide them with something to hold their attention briefly which will be greatly favourable to having them start playing solitaire or minesweeper which is far more likely to eat into their productivity for half an hour or more. Of course any water features will perform many of these tasks to some extent. For instance having water falls will help to create the ambient lighting and sound and will provide a slight distraction (people love running their hands under water falls). However they will not be quite as engaging as having custom aquariums as these include fish.
