Other Anemones in the Wild and Hobby:

Family Actiniidae:

Condylactis species. Though most of these come to use from the tropical West Atlantic as inexpensive "Condys", there are Indo-Pacific species. This one in Fiji.

Anemonia species. Classed as "undesirable" due to its reproductive proficiency, this is an unwanted pest species complex that "comes in" incidental to live rock.

Family Actinodendronidae:

Actineria sp. N. Sulawesi.

Actinodendron arboreum (Quoy & Gaimard 1833). Hellfire Anemone (DO NOT TOUCH). /Wiki:
The oral disc of Actinodendron arboreum has stripes that radiate from the mouth, and can reach a diameter of 10 to 20 centimetres.^[7] The column is elongated when expanded; it has a fairly small pedal disc and is thicker at the distal (upper) end. The tentacles are colourless, around 10 to 20 centimetres long and ramify fractally, being subdivided into branches and branchlets which makes the whole head of tentacles resemble a broccoli. The tentacles grow in whorls as the animal enlarges; the first whorl is six tentacles followed by further whorls of six, twelve and twenty-four tentacles. The first and third whorls of tentacles are endocoelic (set between the mesenteries in the column interior) and the second and fourth are attached marginally. The sea anemone is well-armed with cnidocytes which are of varying lengths, the ones in the central region of the tentacles being least variable. A juv. in N. Sulawesi, Indo.

Actinodendron cf. glomeratum Haddon 1898, Branching Anemone. Low-lying bush-like anemone. Distinctive knobby vesicles on flattened tentacles. Generally greenish in color, open during the day, occurring in sand/mud. Western Pacific; Australia, Philippines. N. Sulawesi pic at night (note Sexy Shrimp at base under sponge).

Where are other Tropical West Atlantic Anemones?

Anemones of the tropical West Atlantic have their own page... to save download time here among other reasons.

About " Colored Anemones":

Yes, sad to state, there are such things... dealers in the orient use chemical dyes to stain mainly "Sebae" (Heteractis crispa) anemones various colors... even country's flag emblems... Sigh, no, the color doesn't last, and I strongly suspect it detracts from their health. Shown, an artificially colored H. crispa and "Sebae" (Clarkii) Clownfish.
