Grew well in my 120-liter reef tank after a few weeks. The coral expanded slowly and maintained a neat dome shape. I feed it once a week with coral food and keep flow low. It’s stable and looks healthy.
Olivia Ogden –
Placed it in the lower section of the tank. It responded well to moderate lighting and regular feeding. Growth is steady, though it’s not aggressive like some other corals.
Phil Springer –
Easy to maintain. I didn’t have to adjust lighting or flow much. After a month, it had developed a nice dome shape. I like how it blends well with other corals in the tank.
