They are relatively easy to care for. Sand bed anemone, care is very similar to Haddoni Carpet or H. crispa. Bright light clean, stable water and not a lot of current. Feeding helps, they eat anything from bits of sea food to flake food.
I keep my pair in a 30 g tank with 4 inches sand bed. They attach to the glass bottom of the tank right in the middle of the tank, under 150 W MH.
