Be the first to add a comment! Quick as a whip, the Small Rock Anemone will retract into its hole or crevice if it feels threatened!Small Rock Anemone Contents Don't be fooled by this quick maneuver, even though a Small Rock Anemone is fast at disappearing if disturbed, that's just one of its fast tricks. This pretty rock anemone, also known as the Glass Rose Anemone, is very fast at reproducing and can quickly overrun its environment. Small Aiptasia anemones don't have a very good reputation with saltwater hobbyists, because they can reach plague proportions in a saltwater aquarium or a reef tank. All Aiptasia anemones have strong stings, and don't "play nice" with other corals and fish. They use venomous cells, nematocyst found in their tentacles, to sting corals and fish. They are very hard to get rid of and have been known to take over a reef aquarium by quickly reproducing while stinging and killing other tank invertebrates. Corals and other anemones are the invertebrates most affected by Aiptasia pests. Unless you are keeping Small Rock Anemones in a refugium to help control nutrients, they need to be removed as soon as possible. Once Aptasia gets a foothold, manual removal to keep populations in check, may very well become an ongoing activity. Despite a bad reputation in the saltwater aquarium industry, the Small Rock Anemone does have redeeming qualities in the scientific world. It is used extensively for studies on growth due to its re-generation properties. It is also being considered for use in medical treatments. A method of using its stinging cells in skin creams to deliver insulin to diabetics in a needle-free way is being explored. Other Aiptasia being used in various types of research include the Glass Anemone Aiptasia pulchella, and the Brown Glass Anemone Aiptasia pallida Family: Aiptasiidae Species: Aiptasia diaphana Sea Anemone Facts: The Small Rock Anemone Aiptasia diaphana was described by Rapp in 1829. Some other common names it is known by are the Glass Rose Anemone and the Trumpet Anemone. Where are Sea Anemones Found: The Small Rock Anemone has a very broad range. It is found in the Mediterranean and Canary Islands, Bali, Indo Pacific, Indonesia, Kenya, Philippines and the Red Sea.. Sea Anemone Habitat: Aiptasia anemones are found in shallow waters along protected coasts and along intertidal rocky shorelines. They are found alone attached to rubble, live rock, dead corals, and other hard substrates.They will also form dense colonies in areas of shallow water, sometimes so dense they look like solid sheets. They occur in deep water too, where there is good tidal action. They generally eat zooplankton, but will always accept other foot particles. Sea Anemone Species: There are 17 species in the Aiptasia Genus. General common names all the various Aiptasia anemones are known by are Aiptasia, Glass Anemone, Glassrose Anemone, Rock Anemone, Devil ’s Plague, Aiptasia Anemone, Pest Anemone, and sometimes by this misspelling, Aptasia. Aiptasia diaphana is not on the IUCN Red List for endangered species Appearance of a Sea Anemone: The Small Rock Anemones are somewhat translucent and generally occur in a brownish or pink to reddish color with lighter tentacle tips. Their coloring comes from an algae called zooxanthellae living in its tissues. Aiptasia diaphana are quite small, only getting up to about 1.2" (3 cm) tall. Their body form is the polyp. It is composed of an elongated column with an oral disc on top that has a mouth in the center. There are elongated tapering tentacles positioned in narrow rings on the outer margin of the oral disc. If it feels threatened, quick as a whip, the Small Rock Anemone will rapidly retract its tentacles becoming a very small ball, and it will retract into its hole or crevice. How do glass anemones move?: The Small Rock Anemone has a pedal disc or 'foot' with which it attaches to the substrate. If tank conditions are not ideal they will use their "foot" to move along the substrate. Aiptasia anemones do this by contracting the circular muscles of the foot and pushing forward, or they may crawl on their side, moving about 4 cm per hour. Aiptasia will Often Aiptasia will simply opt to disconnect and float around, or swim by moving in a spiral motion, until they find a new spot to adhere too. Sea Anemones Life Cycles: It is unknown how long Aiptasia can live, but they do reproduce quickly. Mature specimens can produce dozens of juveniles in a single day if they have plenty of nutrients. Sea Anemone Care: Some aquarists use aiptasia in their refugiums to take out nutrients from the water. Small Rock Anemones are easy to care for and they are quite hardy and durable. They have the ability to reproduce rapidly in saltwater aquariums where there are plenty of nutrients and good lighting. Small Rock Anemones can reach plague proportions in captivity. In some aquariums they will reproduce faster than in others, but the exact reason is unknown. They do seem to reproduce faster in environments high in nutrients and detritus. This anemone as well as any species of Aiptasia is generally regarded as a pest. They can be difficult to control and / or eliminate once they get a foothold. What Do Sea Anemones Eat: The Small Rock Anemone is a carnivore. In the wild Aiptasia derive nutrition from their symbiotic algae, zooxanthellae, as well as from the water around them. They use their tentacles to capture organic matter that floats by, then insert the food into their mouths for ingestion. They generally eat zooplankton, but will always accept other foot particles. Water changes of 10% bi-monthly or 20% a month are typical for most anemones, but with Aiptasia, the more nutrients you have the happier it will be. They will flourish in poor water-quality environments that are rich in organic nutrients. Related Video:
Using aiptasia in refugiums to take out nutrients can be effective, yet it can also be risky if any parts of an aiptasia migrates to the main tank through the filtration. The typical reef environment is best for these anemones. Like most anemone species, they need live rock or some other solid material they can attach to. In a refugium use screening to prevent free floating aiptasia from migrating to your main tank. Be sure to have all of your pumps covered. Most good quality pumps have guards on them.
Compatibility and Social Behaviors The Small rock Anemones are aggressive anemones that have strong stings that can harm, and even kill other corals and fish. Saltwater hobbyists don't purchase these anemones, rather they are acquired accidentally and they are able to out compete other species in the reef tank. When disturbed they eject dangerous white stinging threads, or acontia. By using venomous cells or nematocyst found in their tentacles, they sting and push other inhabitants away from their "turf". They have strong stings that can harm, and even kill other corals and fish. Studies of A. pallida and A. pulchella have determined that Aiptasia individuals are dioecious, meaning that individuals are of separate sexes. However, no sexual difference in appearance is known. Propagating aiptasia anemones is fairly easy, just cut a piece off and it will grow. Anemones in general can multiply by sexual and asexual means. Aiptasia will multiply asexually by fission, which is where a tiny bit of tissue detached from the foot quickly develops into a new and complete anemone. Aiptasia anemones will tolerate their own "clones", and these anemones are very prolific. This is why it is very difficult to physically remove these anemones from a rock. Any remaining tissues quickly multiply into to new specimens. Sexual reproduction has not been described for the species. Problems for the Small Rock Anemone are pretty minimal unless your lighting, water movement, feeding and water quality are low. Then your anemone will detach to look for "better conditions." With better conditions, they can quickly multiply, and having a quickly expanding population of Aiptasia then becomes the problem. Regular and time consuming manual removal is often required so that an aquarium is not overrun by dense populations of Aiptasia. There are various ways to reduce and control aiptasia populations. Sea anemone predators provides a natural, biological method of controlling and possibly eliminating Aiptasia anemones. Other methods include chemical removal and the more risky method of physical removal. There are important considerations when using either of these two methods.

Buy Sea Anemone: Saltwater aquarists don't usually buy Small Rock Anemones, but Aiptasia is available alive from supply companies for research and scientific study. Aquarists generally acquire them as hitchhikers, arriving with live rock or attached to the base of corals..
