You are a doctor. And you are a famous one at that. When people in your city have sick children, they automatically have your name in mind. The kids all love you. And almost all of them don’t feel uneasy when they go visit your clinic. Indeed, judging from the number of people in your waiting area when the clinic is open, you know that a lot of parents really trust you to take care of their children.

The kids go to your clinic and they don’t see a man in a white coat, ready to afflict them with pain. You look like someone who is nice and sweet. Actually, these kids don’t care what the doctor looks like when they see a whole bunch of toys scattered in the clinic’s play area. But for the parents who are stressed out from taking care of their kids, an aquarium is there to calm the senses just by looking at the fish. Of course you do need to have crystal clear water for the fish. But you have no problem with the water getting dark and a little murky. You have one of those Tetra aquarium filters.
