Family Stichodactylidae

Heteractis magnifica

(Quoy & Gaimard, 1833)

Magnifica/Ritteri Anemone or Purple Base Anemone

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-Pacific Ocean: Red Sea to Somoa

Natural Environment: Inhabits shallow reef and lagoon areas having very good water movement where it is usually home to hundreds of various clownfishes and often found in large colonies at depths of 3 to 30 feet (1 - 10 m)

General Husbandry: Formerly called Radianthus ritteri. Has a temperature range of 72 to 82°F (22 - 27°C). Prefers its base attached to rock in open water where there is good water flow and intense light to stimulate its symbiotic zooxanthellae. Its column can be blue, brown, green, magenta, red, or white and its tentacles usually shades of brown, but can also be green, yellow or white depending upon place of origin. When light is insufficient, it may expand to capture as much light as possible. Conversely, when it is too bright, it will retract to reduce the degree of oxygen production by its symbiotic algae. Excessive oxygen can actually damage the anemone tissue structure. Excessive UV produced by some metal halides my also damage tissue structure. It likes a spot in the aquarium that provides moderately strong current and very good light intensity. My personal favorite! Seems to prefer a diet of crustaceans rather than other type meaty foods with five or six monthly feedings recommended. Quite hardy and an excellent host for several clownfish species, in fact, it hosts 12 species. Should be the first 'coral' animal in the aquarium and allowed to roam/find its preferred place before adding other fixed location corals as it will sting anything it comes in contact with.
