Very pretty but could prove to be difficult to care for. I would have a good strong protien skimmer on that tank.
Common Names: Maroon Anemone, Rose Colored Anemone.
Family: Actiniidae.
Scientific Name: Cladactella manni (Verrill, 1899)
Average Size: To about 4 inches across and 2 inches high.
Distribution: Known only from Hawai'i.
Habitat: The intertidal zone along turbulent, oxygen enriched rocky shores residing in crevices or pockets and under ledges that are "constantly" washed by waves.
Identification: The tentacles of this anemone are dark rose in color and sticky to the touch. The column or base may be of a dark rose, maroon, brownish or copper green color, often being so dark in color it appears to be black, and is covered with small rounded bumps (vesicles).
Characteristics: An uncommon anemone, but one of Hawai'i's largest that occurs singly, because of the shallow, heavy wave action, oxygen enriched water environment this anemone requires, it does very poorly in captivity. This anemone does move around and may roam the aquarium very slowly until it locates a spot that it finds conducive to its liking.
Diet & Feeding: Bottom-dwelling carnivore that opportunistically feeds on small fishes and crustaceans. Living in the surge-zone, this animal most likely relies on the turbulent waters to bring food by for it to capture with its tentacles, and may even feed on planktonic organisms. Specific captive care feeding recommendations are unknown at this time.
