Aiptasia sp. (glass anemones) and Majano sp. are often introduced inadvertently into reef aquariums through live rock and coral bases.  If left untreated these pests can destroy coral populations and even kill fish.  Red Sea’s press release reads: Aiptasia have traditionally been hard to remove, as they not only withdraw into rock spaces when they are touched, but they can release thousands of tiny larval anemones (known as planula), causing proliferation of the problem rather than elimination. Treatments such as acids and other strong chemicals may deal with the host aquarium but do not deal with the larval anemones, and any short term effect is usually negated by an increase in numbers of aiptasia. Uniquely formulated by Red Sea, Aiptasia-X is a composition of natural components, formulated into a thick, adhesive mixture that globulates on contact with the aquarium water. It is easily injected near to the oral disk of the anemone and stimulates the anemone to ingest the material without causing it to withdraw into its hole. Aiptasia-X effectively seals the oral disk of the anemone, preventing the release of larval planula into the aquarium, thus preventing a proliferation of these harmful pests. Aiptasia-X is now available in both in the regular 60ml bottle, and now also in 250ml size suitable for larger aquariums, and those with heavier infestations of aiptasia. Both sizes are supplied with straight and curved syringe tips, allowing easy dosing even for those anemones which inhabit undersides of rockwork and other hard to reach locations within the aquarium. A 500ml trade pack is also available.   Aiptasia-X is totally reef-safe, working both effectively and quickly. For a video showing the product in use please go to www.redseafish.com
