hi.
There are two geni under the family Xeniidea, namely,
Xenia and
Anthelia.
Anthelia is often mistaken for
Xenia. The true Xenia have many species, most popular of which is
X. elongata. It is often referred to as the IndoPacific, tree, blue, or brown Xenia. A pinkish variety is from the
Red Sea, and some people call it the pink Xenia. There are also whitish Xenia from Fuji, as well as pompom Xenia. Another is
X. umbella, which is similar to pompom variety, but can be the same thing... So I have about two scientific names, 4 varieties, 9 common names, one of which is a misindentification.
Most Xenia pulses. Some Anthelia also pulses. Some Xenia pulses in one's tank, while the same Xenia don't in others. Some Xenia pulses all the time, other only pulses at night. Some Xenia pulses, but for some unknown reason (computer virus? loud rock music?) stopped pulsing all of a sudden. Some Xenia never pulses before, but after the caretaker dated a new boyfriend, it started to pulse.
Some people dose radioactive Iodine, while some never dose anything. Some people say their Xenia swallowed a small fish, while other say it does not even have a mouth/stomach. Some people dose sodium nitrate, while other tried to keep nitrate at 0ppm. Some people never has one live more than two weeks, other flush Xenia down the toilet like v^hit. Some people put it under MH, other grow it well under NO. Some say they like low current, other say they only happy right in front of a powerhead.
Did I confused you enough yet?
