Heteractis aurora
Swellings run along the tentacles, either on one side only or almost all the way round, giving the look of beads on a string; a single tentacle may carry up to 20. The broad flattened oral disc reaches 250 mm across.
Heteractis aurora occurs from Micronesia and Melanesia to East Africa, the Red Sea, and from Australia to the Ryukyu Islands. It lives among coral and along rocky reef edges and slopes, normally where currents are strong. It attaches to a surface and remains partially buried in sediment or sand, withdrawing entirely into the substrate when threatened; SeaLifeBase records a depth range of 0-19 m. Both tentacles and oral disc are brown or purplish. The tentacles reach 50 mm, may be sticky to the touch and sometimes have magenta tips. The longer tentacles carry swellings on one side only or almost all the way round, giving the appearance of beads on a string, with up to 20 on a single tentacle. The broad flattened oral disc reaches 250 mm across and may show white or brown markings radiating from the centre and continuing along the tentacles. It hosts seven species of anemonefish.

Nutrition from symbiotic zooxanthellae, supplemented about once a week with meaty foods such as fish, shrimp and clam.
It is a zooxanthellate anemone and does require illumination.
In the wild it chooses positions with strong currents. It attaches to a surface while keeping part of its body buried in sand or sediment, so it needs a layout offering both rock and a sand bed.
Keep it within the care parameters LiveAquaria lists for anemones of this family: 22-26C and a specific gravity of 1.023-1.025.
Besides photosynthesis, offer meaty foods such as fish, shrimp and clam. It withdraws into the substrate when disturbed, so watch its response while feeding.
This species is sometimes traded under the Japanese name of Entacmaea actinostoloides; its own standard Japanese name is juzudama-isoginchaku. It is not listed in the CITES Appendices.
