Acanthastrea (Acanthastrea sp.) / Micromussa (Micromussa Lordhowensis)LPS corals, formerly referred to as Acanthastrea or Acans, were reclassified and grouped together with the Micromussas corals. Now they are both taxonomically listed as Micromussa lordhowensis, though many hobbyists still refer to them as Acans. Even prior to their grouping, the two were very similar with only minor differences. They are easily propagated and as a result are available as an aquacultured coral, but they are native to the Indian and Pacific Oceans. Place them in an area where they will get moderate to high light and moderate flow. These encrusting corals are a hardy, quick growing, large polyp stony coral and should be given some space to grow. They have symbiotic zooxanthallae but they can be fed with a variety of small meaty foods, as well as with coral food. Wait to feed them until they have opened up and extended their tentacles. Micro Lords can be prone to bacterial infections, so make sure to keep an eye on them and always dip them before putting them into a reef tank. Acclimate them slowly and allow them to get used to their aquarium.
