Green Star Polyp / Pachyclavlaria

The Green Star Polyp (Pachyclavularia violacea) is one of the most popular soft corals in the hobby — bright, fast?growing, and perfect for adding instant movement and colour to any reef aquarium. Its vibrant green polyps sway beautifully under flow, creating a soft, grassy effect that brings life to rockwork, back walls, and islands.

GSP is hardy, adaptable, and thrives in a wide range of tank conditions, making it an ideal choice for beginners and experienced reef keepers alike. Once settled, it forms a glowing mat that spreads across surfaces, creating a stunning neon carpet under blue lighting.

Why Choose GSP?

The Green Star Polyp is one of those corals that just makes reefing feel easy. It’s bright, fast?growing, and instantly transforms any dull rock into a glowing, grassy carpet of movement. Whether you’re new to the hobby or building a mature mixed reef, GSP delivers colour and life without demanding much in return.

It adapts well, thrives in a wide range of conditions, and adds that soft, flowing motion that makes tanks look alive. If you want a coral that’s reliable, eye?catching, and guaranteed to stand out under blue lighting, GSP is an effortless win.

Care Tips for GSP

• Give it space to grow — GSP spreads quickly once it settles, so placing it on an isolated rock or island helps you control where it goes.

• Stable water parameters — It’s forgiving, but like all corals, it thrives best in a stable, mature system.

• Moderate flow keeps it happy — Enough movement to make the polyps sway, but not so strong that they stay closed.

• Lighting flexibility — GSP glows under blues but will adapt to almost any lighting setup, making placement easy.

• Regular maintenance — If it starts creeping where you don’t want it, gently peel or trim the mat to keep it contained.
