A reef aquarium filled with many different species and types of coral can be a very rewarding and enjoyable experience. Water quality is the most important aspect of keeping a thriving reef environment that is both suitable for the fish and invertebrates while keeping the tank visually pleasing The primary aspects of water quality do not differ much from keeping fish-only aquariums. However, the addition of corals will add a new dimension with more parameters to monitor for healthy, growing, and vibrant corals and fish.  These include calcium, alkalinity, magnesium, phosphate, pH, ammonia, salinity, and temperature.

Puffer fish have teeth that grow continuously and need to be continuously worn by proper hard food items found in their wild diet.  In captivity they will often have problems with overgrown teeth due to soft captive diets.
