Ryan Robertson –
The branching hammer coral grew quickly after a few weeks. The neon green tips stand out well in my tank. I feed it daily with mysis shrimp and keep the lighting strong. It’s a great addition to a mid to upper level display.
Lisa Jones –
It’s vibrant and active. I noticed it extends its branches when water flow increases. Needs consistent feeding and a bit of attention, but worth the effort.

Installed it in the middle of the tank with medium to high flow. It has expanded nicely and looks healthy. The color is bright and stands out against the background.
