MARINE INVERTEBRATES
Marine invertebrates are sometimes more difficult to keep in an aquarium: on
the one hand, they are very sensitive to the quality of the water, which must be
as faultless as possible, and, on the other, feeding them is complicated, particularly
in the case of sponges, Coelenterates, anemones, and corals. It is also important
to consider the compatibility of invertebrates, not only with each other but also
with fish — as invertebrates are the favorite meal of some fish!
For all these reasons, the best option is a specialist tank, which will provide
a spectacle just as fascinating as that of a fish aquarium, although those fish
which can cohabit with invertebrates represent a logical complement to this type
of aquarium. The invertebrates which are most robust and easiest to acclimatize
can reproduce in captivity (especially some species of anemones), but success in
this area requires a solid background in marine aquariums on the part of the hobbyist.
Nevertheless, some marine aquarists hesitate to cross the threshold from fish
to invertebrates, on the grounds both of cost and risk. However, these days there
is a craze for this type of aquarium, but you must not get carried away: it is not
feasible to reconstitute a coral reef, although it is possible to achieve satisfying
results, both in terms of ecological equilibrium and an engrossing spectacle.
