Although several anemones are commonly called Sebae Anemones, this record is concerned with the species Heteractis malu. There is much controversy concerning the ease of care of these anemones; some claim they are hardy once established, while others claim that Sebae Anemones are rather difficult to care for.
The Sebae Anemone is often a good host for certain shrimp, Damsel Fish, and Clown Fish. Sebae Anemones may react aggressively, however, to non-symbiotic species in their aquariums. They can be sensitive to toxins or chemicals released by other anemones. Often, the presence of other anemones may harm Sebae Anemones. These anemones generally require bright lighting and a moderate current. As with all anemones, water quality should be kept high.
A wide variety of colors are seen on Sebae Anemones. However, some colors are dyed onto the anemone, rather than occurring naturally. Naturally occurring colors include white, pink, red, cream, yellow, and tan. These anemones are often dyed yellow and pink. When the base and tentacles are different colors it indicates natural coloring. Some Sebae Anemones may take on greenish hues when viewed under actinic lighting. Often, the tips of the Sebae Anemone's tentacles are magenta in color, but some specimens have yellow-green tentacle tips. Sebae Anemones that are tan in color seem to live longer than other specimens, particularly white ones. It is believed that white Sebae Anemones may have lost most of the symbiotic algae that provides food for them, and many claim that white specimens do not live long and may not thrive.
They are generally not long lived in captivity, and many people contend that despite their relative abundance in the pet trade, these anemones may not be the best choice for a beginning marine aquarist. The widespread disputes over the characteristics and ease of care of Sebae Anemones may be exacerbated by the application of the common name Sebae Anemone to multiple anemone species.
