INVERTEBRATES

These days, more and more aquarists seem to be taking an interest in these animals. Ecologically speaking, invertebrates represent a natural complement to fish and plants; in visual terms, you can put on a spectacle of luminous beauty, particularly in sea water, using anemones and corals, to which can be added small fish, either lively or placid, but always brightly colored. There are also a few species of freshwater mollusks and crustaceans which are easy to keep in captivity, although they are little known and often overlooked.
