In the reefkeeping community, 'Acan Coral' commonly refers to several species within the Acanthastrea genus. However, some species previously classified as Acanthastrea have been reclassified - for example, A. lordhowensis is now considered a Micromussa, and A. bowerbanki has been moved to the Homophyllia genus. Despite these taxonomic changes, these corals are still widely referred to as Acans when searching or filtering in the hobby.

How to Choose a Healthy Acan Coral
- Polyp Health:
Healthy Acans should have inflated, fleshy polyps that are responsive to light and movement. Avoid specimens with deflated, recessed, or damaged tissue.
- Growth Signs:
Frags showing new heads forming around the edges at the base are actively growing and generally healthy. This is a good sign of stability and low stress.
- Fresh Cuts vs. Healed Colonies:
Healed frags with visible tissue growth over the skeleton are more stable than fresh cuts. However, fresh frags can still thrive with good care.
