Dan Mitchell –
Installed the coral in my 120-gallon reef tank after a few months of acclimation. It has grown steadily and shows vibrant coloration. The lighting is moderate and current is low, which matches the requirements. No issues with tankmates so far. I’ve been adding calcium and strontium weekly as recommended.

It looks beautiful with its mushroom-like appearance. The colors are vivid and it’s stable in my tank. I keep the flow gentle and use moderate lighting. It hasn’t shown any signs of stress or aggression. A good addition to a balanced reef setup.

After a few weeks, the coral expanded its polyps and now covers a good portion of the rock. I followed the care guide and added trace elements regularly. It’s peaceful and blends well with the other corals. Very satisfied with the purchase.
