Hypnea is one
of only a few species of purple-blue macro algae species available in
the United States. It's similar to the rarer Caribbean algae ochtodes,
but has finer branches and some iridescent qualities. Since it's
importation to the U.S. it's become a very popular algae for the
marine aquarium. It features coarse,
bushy, compact branches that grow as small clumps or mounds. With
bright light the algae will often turn a blue-green color on the
top. It's hardy and grows quite well in captivity, but can also be
a bit difficult to keep long term as it doesn't like sudden
changes in salinity, temp or ph which can cause it to die back.
It's not very palatable to fish or invertebrates.
