Rock Flower Anemone


Rock Flower Anemones are ideal additions to a saltwater aquarium, being hardy plants that tolerate moderate lighting levels and are great extras for pico or nano tanks.

Carnivorous in nature, sea cucumbers require meaty foods. Their 200 tentacles capture and devour small fish, such as shrimp or clams, for sustenance.

They prefer a moderate water flow with varied movement patterns in their tank. Too high or too low of an intake can put undue stress on them and even result in serious health concerns.

Rock Flower Anemones (RFAs) are smaller sea anemones found in the hobby and make an eye-catching addition to an aquarium filled with pricey coral frags. Beginners looking for an attractive tropical aquarium with limited tank space should consider buying sea fans, as they bury themselves on the sandy substrate and only show their oral discs and tentacles. Rock Flower Anemones don’t wander about aimlessly like other sea anemones, which may sting corals they come into contact with. Even though they may only reach 5 cm in size, these beautiful displays boast wide color morphs with short arms ranging from smooth to jagged textures – making a stunning display! These anemones reproduce sexually and asexually and can grow to 6″ in diameter!

Rock flowers offer another advantage: they pair well with many corals and invertebrates, including peaceful gobies, pistol shrimp, and cleaner shrimp, to create an engaging marine scene. Blennies add color while their unique behaviors provide endless entertainment, and Zoanthids, with their vibrant hues, also complement rock flower anemones perfectly.

Rock flower anemones require ample room and light to thrive and enjoy their surroundings and need an environment that replicates day and night cycles like those found in nature. You can provide these photosynthesizing creatures with meaty foods like small shrimp, mussels, or frozen fish food as food sources to promote optimal health.


Rock Flower Anemones (RFAs), commonly referred to as RFAs, are famous for their bright tentacle colors. RFAs attract hobbyists and add an attractive splash of color to any saltwater aquarium, naturally found throughout the Caribbean near shadier coral reef drop-offs.

As they are semi-aggressive creatures, octopuses can often be found alone or in groups and prefer living on shaded vertical rock walls or substrates. Once settled and protected from predators, they bury most of their bodies except their oral discs and tentacles to give hobbyists an ideal view of tentacles waving in the current.

If a coral is unhappy in their current location, they can use its oral disc to absorb water and move. Corals are hardy creatures who can adapt to various lighting conditions; the optimal environment would provide medium-light with medium to high water flow rates.

Like most anemones, rock flowers contain nematocysts – stinging cells used for self-defense against predators – that may trigger human skin reactions when handling or working in your reef tank. While typically harmless to fish, rock flowers will sting if approached too close or try to steal their food source.


Rock Flower Anemones make a beautiful addition to any reef aquarium, as they are hardy creatures capable of adapting to different lighting conditions. Commonly found in the Caribbean, these anemones are beloved among aquarists for their vibrant color patterns and beaded tentacles. Housed alone or in groups, they usually prefer shaded rock walls or sandy substrates where they bury themselves into the soil, only showing their oral disc and tentacles when visitors come around.

Rock flower anemones are photosynthetic animals and receive most of their nutrients through an intimate partnership with coral zooxanthellae, but they also enjoy receiving regular feedings of small meaty snacks at least once every week. When hungry, their tentacles protrude and become noticeably stickier to attract and capture food into their tentacles.

Rock anemones should be gradually introduced into aquariums to avoid shock or stress when transitioning from pet store water. For optimal results, keep them in an environment with low lighting and moderate water flow for several days before moving them to their permanent homes – they tend not to move around much once settled into place!


Rock Flower Anemones are hardy and straightforward to care for, making them an excellent choice for beginning aquarium enthusiasts. They thrive when placed in an aquarium substrate or sand bed with moderate levels of light and water flow; additionally, they enjoy having a rocky reef structure attached to their tank where they can attach themselves. Once found, they tend to stay in one spot.

Complete carnivores thrive when fed a diet of mussels, chopped fish meat, and other frozen foods like mussels. Regular doses of iodine and trace elements will be beneficial. Direct feedings should occur approximately thrice weekly through a pipette or turkey baster, while they will also extract food from the water column during broadcast feedings.

Since they are small, small fish are ideal candidates for rearing in nano aquariums and display tanks. Furthermore, their vibrant colors add terrific visual interest, character, and beauty to a reef environment.

Remember that anemones do not like to be dunked in water and may lose some tentacles during this process. Therefore, it is wise to quarantine new anemones before adding them to the main reef tank.
