Biotope Tanks

Any display of reef fish impresses with bold colors and constant motion. For sheer fascination, however, minireef aquariums offer more than any fish-only tank can. Defining what, exactly, constitutes a minireef depends upon whom you ask, but a typical example features sessile invertebrates and live rock. Fishes, if included, are species that will leave the invertebrates alone. Beyond that basic pattern, aquarists have set up everything from minireefs devoted to different color forms of the same coral to aquariums seeking to duplicate the look of an actual reef biotope. The latter approach forms the basis for this chapter.
