Acans are active feeders capable of grabbing passing food with their tentacles which appear when their polyps are expanded. They grow by forming new polyps at the edge of existing ones and as the polyps get larger they lay down new skeleton.

This family of Acans - Acan Lordhowensis - can be kept close together without fighting but allow some distance from other corals.

This Acan is bright green with a contrasting tan edge.

Frags will be between 4 and 6 polyps.

How long we've kept this coral: 11 years.


  • Feed regularly for faster growth with meaty foods such as brine and mysis shrimp.
  • Calcium and alkalinity levels are important for all corals but especially so for LPS - for tips on maintaining the correct levels see the Reef Chemistry page.
