A variant of Acropora coral (Acropora sp.)

Representative Acropora coralphoto — a dedicated image of this exact morph isn't available yet.
An Acropora tortuosa famous for its deep true-blue branches, forming a dense bushy colony — one of the great workhorse 'gateway SPS' acros.
📜 Backstory
A legendary US frag-trade lineage that has circulated for well over a decade. Origin is debated in detail, but it is widely reported to trace to a maricultured Indo/Pacific (Bali/Solomon-sourced) tortuosa that turned deep blue in a Portland, Oregon shop and spread from there — hence the locale name, which refers to where the strain was grown out and distributed, not where the coral was collected. Decades of propagation make it affordable and ubiquitous.
Keeper tips for this variant
Adaptable but colors best high in the tank under strong light and flow; an excellent first acro because the blue holds across a range of conditions. Slow to start, then faster once established.
