Coral Line by: Karen & Christopher Stewart Coral Type: Digitate Coral species: Acropora humilis 2 yr update:WOW! This line is amazing! The coral bleaching event induced by El Nino occurred in April 2016, so your line was left in the nursery to wait out this event. Transplanting to the reef would have caused unnecessary stress. We believe we made the right management decision as the line, following bleaching, has recovered well, with 100% survival! On our reef, this species can no longer be found, as all were killed in the bleaching event. This means your line is so important for re-seeding our damaged reef!
