Galaxea does not require as much light as some other corals. It can be kept under normal output fluorescents without much difficulty. In our experience this coral does poorly in medium to high light reef aquariums.

Moderate flow is recommended.

Galaxea relies heavily on the products of their zooxanthellae. This coral may benefit from finely ground meaty foods. The food should almost have a paste-like consistency before being administered due to the small size of the polyps. 

Keep in mind this coral has long tenticles (sweepers) at night, or feeding time and potentially could bothers and kills coral next to it. Best placement 6+ inches away from other coral, or on island. Grow pattern as GSP.
