Knobbly Sea Rod Gorgonia - Eunicea mammosa | Hardy and Structuring Gorgonian for Reef Tanks

The Knobbly Sea Rod Gorgonia (Eunicea mammosa) is a sturdy and striking gorgonian, perfect for adding height and movement to a reef aquarium. Native to the coral reefs of the Caribbean and Western Atlantic, this species features thick, knobby branches covered in delicate polyps that extend in good lighting. As a semi-photosynthetic gorgonian, it absorbs some energy from light while also requiring supplemental plankton feeding. This species is an excellent choice for aquarists looking for a resilient and decorative addition to their reef tank.

Key Benefits:

✔ Hardy gorgonian – Tolerates various reef tank conditions.

✔ Semi-photosynthetic – Absorbs energy from light but benefits from additional feeding.

✔ Provides natural structure – Offers habitat and shelter for fish and invertebrates.

✔ Reef-safe – Does not harm fish or corals.

✔ Natural swaying movement – Polyps gently sway with water flow.
