Sonic the Hedgehog Galaxea
Sonic the Hedgehog Galaxea has been running around reef tanks since at least 2018, making it one of the older named Galaxea still commonly passed around today. Bright neon green polyps with blue tones give it that classic electric look.
Most Galaxea have a reputation for throwing long sweeper tentacles at anything within reach, especially gold varieties. In our tanks, Sonic is much better behaved and keeps its sweepers considerably shorter, so it can live reasonably close to neighboring corals without constantly starting trouble.

We recommend starting the Sonic the Hedgehog Galaxea in the 100 - 200 PAR range.
Flow — Moderate
Moderate
Provide Moderate variable flow that keeps detritus from settling on the Galaxea. Avoid constant direct current from the same direction in favor of random chaotic water movement.
Placement — Lower level
Placement of your Sonic the Hedgehog Galaxea is one of the most important decisions.
This is where you’ll have to take lighting, flow, future growth and nearby corals into consideration.
Since it prefers 100 - 200 PAR range it will need to be mounted Lower level on your rock work depending on your light intensity.
Allow room for its Encrusting growth form, and consider neighboring coral colors and shape. When possible, use contrasting corals such as red next to green, blue next to orange, or yellow next to purple, and mix growth forms such as tall branching corals next to plating or encrusting corals.
