Coral Hitchhiker ID

[SAMSHUNG]

Good point, I hadn't considered that. It was listed as Jakarta Live Rock when I purchased it and judging from other Indonesian LR that I've seen I think it's accurate. It was purchased from Pacific Aquatics in Surrey (incidentally they currently have it on sale for $5.75/lb). Are Sun Coral and Dendros indigenous to that location? Also, as both Sun Coral and Dendros have differing requirements how might I tailor it's husbandry until I determine exactly species it is?

Sorry for all the Q's but I'm a total n00b still.
