Speedstar,
Thank you for your wonderful comments on our packaging. We were very excited to procure some fantastic Acropora efflorescens from Bali at the beginning of the month, and after quarantine, offer them for sale in the Divers Den section of the LiveAquaria.com web site. We have a few more specimens left that we are holding for brood stock so that we may grow out and use for propagation in our coral farm.
The identification of Acropora spp is very difficult when dealing with corals that have a similar appearance and growth pattern. Acropora solitaryensis and Acropora efflorescens look very similar, and these corals harvested for the aquarium trade may in fact be confused by all of us in the aquarium industry.
There are a few characteristics that may differentiate the two species according to Veron and Wallace. Acropora efflorescens has no differentiation between the axial and radial corallites. The corallites around the rim or perimeter of the plate grow horizontally, and on the upper plate surface they are perpendicular to the colony, and face upwards. Efflos also have little or no defined corallites structure on the underside of the colony. Acropora solitaryensis on the other hand are distinguished by having fused, irregular base branches. The radial corallites are tubular, with nose like openings on the peripheral parts of the colony.
Both of these corals grow to over six feet in diameter in the wild. In order to properly identify each species correctly we would need to see much larger colonies, in their natural environment. Acropora solitaryensis and Acropora efflorescens are very beautiful; with their distinct plate like growth forms, they are unique among the more common branching species that are prevalent in the aquarium trade, making them highly desirable to the avid Acro collector. Best of luck with your new purchase and enjoy your new prized specimen.
Happy Reefing,
