Common names: carnation corals, cauliflower corals, tree
Natural origin: Indo-Pacific
(Level 5): These soft corals do not survive long in aquariums.
Even the most experienced aquarists find them nearly
impossible to keep alive for very long.
are azooxanthellate corals with exceptionally heavy feeding
requirements. This demanding feeding requirement is probably why
they don't survive long in aquariums. Heavy feeding of
phytoplankton and very fine particle foods in tanks with large,
well-populated sand beds may help delay death. However, even with
the most ambitious efforts, they almost always perish within less
than a year.
Lighting (Level 0 to 6): These corals don't
need light. Too much light can be detrimental.
Strong, alternating, laminar water flow is crucial.
Placement: Contrary to how most aquarists place them,
in the wild, they are usually found growing "up-side down,"
hanging off rock ledges.
General: Unless you are an
exceptionally experienced aquarist wishing to do some thoughtful
experimenting, please do not purchase these corals. Even science
is not entirely sure of their nutritional needs or what all they
feed on in the wild.
