Approx 3+ cm
Chalice coral needs appropriate lighting and moderate flow to be healthy and grow. It will also require the correct levels of Calcium, Alkalinity, and Magnesium etc to thrive within your system!
Additional feeding isn’t required to maintain its health.
Be sure not to place it too close to other corals as at night it will release its sweeper tentacles which will sting other corals resulting in damage and a lot of time even full loss!
