The relationship between bacteria and corals has recently become a hot topic on Reef2Reef as a result of a research paper recently published in the Nature journal. The study estimates that about 1/3 of all corals worldwide are infected with this newly discovered bacterium which researchers named Candidatus Aquarickettsia rohweri. The bacterium can be found in a number of corals that we commonly keep in our aquariums including Acropora, Goniopora, Montipora, Seriatopora, and Stylophora species. Additionally, it can be found in anemones.
