Minireef aquariums owe much of their appeal to invertebrates. The fish may, in some designs, be secondary players. Even in a fish-only aquarium, a few carefully chosen invertebrates help solidify the illusion of a natural biotope. Invertebrates add color and interest, and in some cases reward the aquarist by reproducing themselves. Many sessile invertebrates grow and spread like garden plants. In time, the aquarium begins to take on a truly natural look that cannot be otherwise achieved.
I find it useful to categorize the hundreds of invertebrate species available to aquarists in two ways, either by their biological classification or by their ecological roles in the aquarium.
