Granny Smith Goniopora

Bright apple-green and in constant motion, this Goniopora is the kind of coral that makes people stop at the glass — and also the kind that's quietly humbled plenty of experienced reefers. The genus is notorious for fading out in tanks with otherwise pristine parameters, likely down to trace element and stability demands nobody's fully cracked. If your system's been running clean and stable for a while, this is a rewarding centerpiece; if it's still finding its legs, let it mature first.

Care level: Moderate-difficult · Light/Flow/Placement: Moderate light, low-moderate flow, bottom-to-mid tank · Max size: Expanding polyp mat, several inches · Diet: Photosynthetic, fine particulate feeding
