It can't be A branchi. Where they are present the regions don't export corals to the US/Canada. It's a Bali mari plug so it's gotta to be a species from Bali.
How can you tell the origin of the plug from those photos? Its out of focus and covered in algae. I didn't know that the plug design was specific to a given region.
LOL I cheated.. But actually you can typically somewhat tell by the plug each region / facility I believe makes there own plugs based around how there farming area is setup, and there aren't that many places doing mariculture.
I've seen a few different types of plugs
The lumpy Bali ones with the bottle caps are the most common
Smooth ones I don't see very often anymore (with a bottle cap in the bottom fiji)
There fiji ones that have a "spike" on the bottom.
Then SI are discs shaped.
The new "bali" deep water stuff seems to be a smoother plug flat bottomed hand formed disc.
:headwally: Well next time include such information for the rest of us rather than trying to play expert.
I've also seen quite a few different plug designs. I know Walt Smith's Fiji Acropora usually come on a specific plug. Beyond that it seems like trying to judge the origin based on the plug is a futile effort. Lets not forget that many of the countries engaged in mariculture are 3rd world countries and consistency with the plug design is (I can only imagine) not exactly a priority. I could be very wrong though...
Now, as you said, if we know if comes from Indonesia, then the search is narrowed.
