(*Formally the word symbiont includes harmful interactions like parasites).

Although this coral symbiont is widespread in nature, its relatively rare in aquarium samples. 

A. rohweri was detected in less than 3% of the samples we've tested.
When present, this bacterium generally makes up a very small fraction of the community (0.1% or less).
