Family Actiniidae

Anthopleura xanthogrammica

(Brandt, 1835)

Giant Green or Surf Anemone

Not Reef Tank Suitable

Not Suitable for Fish-Only Tank

Range: Pacific coastline from Alaska to Panama

Size: Column width 12 inches

Natural Environment: Inhabits intertidal sandy or rocky shorelines, and sometimes found in deep channels of more exposed rocky shores and concrete pilings in bays and harbors.

General Husbandry: Has a temperature range of 59 to 72°F (15 - 22°C). Zoochlorellae and zooxanthellae provide nutrients to the anemone via photosynthesis and contribute to the bright green color of the anemone's oral disk and tentacles. Yet capturing sea urchins, small fish, crabs, and mussels is its main food source.

Rarely collected, and requires cool water and hand feeding, e.g., raw fish pieces, shrimp, tubifex worms, and is especially fond of mussel flesh. Two to three feedings per month suffices in cool water environments.

Aquarium Suitability: For those interested in maintaining a cool water aquarium, this species is quite hardy; otherwise, it should not be collected!
