Nuclear Metallic Trachy

About this coral

Nuclear Metallic Trachy is a sandbed LPS “trachy” coral sold under this shop name, typically referring to Trachyphyllia open-brain corals in the Trachyphylliidae group. These corals are known for their fleshy, ridged “brain” look and are usually kept on the sand rather than glued to rock. In practice, they’re a great choice for reef keepers who want a feeding-capable LPS that responds well to stable water conditions and gentle, targeted feeding.

Features:

• Fleshy, open-brain style LPS coral often kept on a sandy substrate for natural behavior.
• Generally prefers low to gentle water movement; strong flow can irritate thick tissue and increase stress.
• Best results come from stable, well-maintained reef parameters (especially avoiding swings in alkalinity and other major elements).
• Target feeding supports health; many LPS respond well when food is offered directly to the coral’s extended polyps.
• Aimed placement on/near the sandbed helps reduce physical disturbance and keeps the coral settled.
• Group-level guidance: Trachyphyllia are sensitive to fluctuations, so gradual acclimation and consistent supplementation routines are important.

Specifications:

• Confirmed coral group: Trachyphyllia (open-brain LPS; often associated with Trachyphyllia geoffroyi in trade references) ([boodleshireaquatics.com](https://www.boodleshireaquatics.com/post/coral-profile-trachyphyllia?utm_source=openai))
• Placement: Sandbed; often free-living/settled on sandy substrate ([repository.library.noaa.gov](https://repository.library.noaa.gov/view/noaa/423/noaa_423_DS1.pdf?utm_source=openai))
