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.

Galaxea are notorious for long sweeper tentacles that can sting nearby corals. Give this coral plenty of space to minimize aggression.
