Heteractis malu is known as the Sebae or Leather Anemone. It was previously named Radianthus keukenthali. Heteractis crispa may also be called the Sebae Anemone. Heteractis malu is usually light tan to brown in color, and may have purple tips on its tentacles.

Acclimation to aquarium life can be very difficult for this species and its care should only be attempted by the most experienced aquarists. In the aquarium it requires strong lighting, porous live rock, and a variety of sandy and rocky locations from which it can choose to live. The addition of a Clownfish, such as the Blue Striped Clown, Amphiprion chrysopterus, will immediately help with its acclimatization and improve its chances of survival. When healthy, it will become very sticky. If it grasps onto something (or someone), it will be very difficult to convince it to let go without damaging it.

Once acclimated, it should be fed a diet of fish, worms, clams, shrimp, and other meaty foods once a week.
