The first observation of the Opae`ula is that they like to be on the rocks. An observation is that the shrimp is from the big island or Hawaii island. The food the Opae`ula or shrimp eat is Spuralina. Opae`ula is two words together in Hawaiian definition opae is shrimp and ula is red so it means red shrimp. when I observed them the shrimp ate upside down. the shrimp is brought by plane not boat. by the end of summer school we would be able to take some home.
