The species selection criterion was based mainly on the growth rate faster in captivity, choosing to choose SPS corals of the order Scleractina (formers of limestone skeleton): Montipora Confusa , Montipora Undata , and Montipora Danae ; and a species of soft coral of the order Alcyonacea: Gorgonia Eunicea , selected for similarity in behavior and growth with species of cold water gorgonians from the Portuguese coast.
Corals can reproduce sexually, releasing large numbers of eggs and sperm into the water to distribute them around or asexually, through fragmentation. For this case study, we used the asexual propagation method. The selected species were segmented into units of approximately 10 x 18 x 8 mm3 to be inserted and fixed in the central cavities in the center of each substrate
