Flower Tree Coral.
The Red/Orange Flower Tree Coral is also referred to as the Scleronephthya Strawberry Coral, or Pink or Orange Cauliflower Coral. It closely resembles members of the Dendronephthya genus, and is somewhat easier to maintain. The stalks, branches, and tips of this coral tend to be various shades of the same color. It is a relatively peaceful coral colony. It is normally shipped attached to a small piece of live rock or rubble.
It is moderately difficult to maintain in the reef aquarium and should be housed in an established reef aquarium by the experienced marine aquarist. The Flower Tree Coral will require low lighting levels combined with medium to strong indirect water movement. These corals will not usually fully open in direct water current, so water flow provided by a power head directed at the glass or nearby rock is ideal. For continued good health, the addition of strontium, iodine, and other trace elements to the water.

It is normally shipped attached to a small piece of live rock or rubble.
