First Due Aquatic Rescue Informational Guide For Zoanthids & Palythoa 

Zoanthids and Palythoa, often called "Zoas" and "Palys," are some of the most popular corals in the reef hobby — and for good reason. These colonial polyps grow in colorful mats and come in an endless variety of morphs, from glowing neon tones to intricate patterns that rival the most exotic SPS. Under blue actinic lighting, they often fluoresce with unmatched brilliance, making them a favorite for creating vibrant, living “gardens” of color on rockwork or frag plugs.

Zoanthids and Palythoa are generally hardy, making them excellent corals for beginners while still being highly collectible for advanced aquarists. They adapt well to a wide range of lighting and flow conditions, though moderate light and gentle to moderate flow often yield the best results. Their colonial nature allows them to spread steadily, creating dense clusters that can quickly fill open space in the aquascape.

It’s important to note that Palythoa and some Zoanthid species may contain palytoxin, a naturally occurring defense compound. While they are safe to keep, handling them with care — using gloves and eye protection during fragging or repositioning — is recommended. With proper respect and handling, they remain among the safest and most rewarding corals in the hobby.

Whether you’re building your first reef or curating a collection of rare morphs, our Zoanthid and Palythoa selection at First Due Aquatic Rescue offers both beginner-friendly colonies and high-end showpieces. From bright beginner packs to rare named strains, Zoas and Palys are the ultimate choice for adding lasting color, movement, and personality to your reef.
