Abstract
With the clownfish darting around vibrant green plants and red coral, the 180-gallon saltwater aquarium in my son's pediatrician's office always grabs my attention. For a moment, I get to see how life under the sea operates-and I'm amazed. Maintaining a saltwater aquarium is challenging. Many aquatic species require extremely specific pH, salinity, temperature, and lighting. If something is slightly off, they die. From the rocks to the water temperature, each aspect requires constant care.
