Whether you are looking for classic branching neon varieties or ultra collector-grade holographic morphs, our carefully curated collection offers stunning centerpieces for reef keepers at every level.
Why Choose Hammer Corals?
-
Captivating Visual Movement: Unlike rigid corals, Hammers add fluid, rhythmic motion to your rockwork, bringing a natural ocean-reef energy into your display display tank.
-
Beginner-Friendly Hardiness: Once acclimated to a cycled, stable reef system, Hammer corals are incredibly resilient. They adapt well to standard reef environments, making them a fantastic first stepping stone into stony coral keeping.
-
Vibrant Fluorescence: Under blue actinic lighting, Hammer coral tips glow with intense fluorescence, showcasing brilliant shades of gold, toxic green, deep purple, and orange.
General Care & Placement Guide
To ensure maximum polyp extension and long-term health, place your Hammer corals in the lower-to-middle regions of your aquarium rockwork. They thrive under low-to-moderate, indirect lighting (approx. 75–150 PAR) and prefer a gentle, swaying water flow. Avoid placing them directly in front of high-pressure wavemakers, as intense flow can tear their delicate flesh against their sharp skeletal structures.
Note: Hammer corals possess stinging sweeper tentacles. While different Hammer varieties can generally touch one another safely, please provide at least a few inches of clearance from other coral families to prevent aggressive stinging.
