The Ultra Rock Flower Anemone is one of the most colorful and distinctive anemones available for saltwater reef aquariums. Featuring vibrant combinations of red, orange, green, pink, purple, and other contrasting colors, each specimen offers a unique appearance that makes it an eye-catching addition to any reef display.

Unlike many other anemones, Rock Flower Anemones generally settle into a preferred location and remain relatively stationary once established. They typically attach their foot to rockwork or crevices near the sand bed, displaying a beautiful circular arrangement of colorful tentacles surrounding their central oral disc.

These hardy, photosynthetic anemones are well suited to established reef aquariums with stable water parameters. They are generally compatible with peaceful reef fish and many invertebrates, although their stinging tentacles can irritate neighboring corals.

Aquarium Requirements:

• Established saltwater aquarium

• Moderate reef lighting

• Low to moderate, indirect water flow

• Stable salinity and water parameters

• Rockwork or crevices for secure attachment

• Adequate spacing from neighboring corals

Diet: Primarily receives nutrition through photosynthesis. Supplemental feeding with small portions of mysis shrimp, finely chopped marine shrimp, or other appropriately sized meaty foods can be offered occasionally.

Important: Colors and patterns vary between individual specimens. Ultra Rock Flower Anemones are sold in assorted colors unless a specific specimen is identified.
