The Open Brain Coral (Trachyphyllia) is one of the most striking large-polyp stony (LPS) corals, with a fleshy, inflated body that spreads out like a blooming flower in vivid colors. It's typically kept resting on the sand bed or tucked among rockwork rather than mounted, and it sways gently with the current. One of its most rewarding traits is how readily it responds to feeding — watching it extend its mouth to take in food is a highlight for many keepers. Alongside photosynthesis, regular feeding is essential to its care. With attentive husbandry, it can live for over a decade, making it a coral worth building a long-term relationship with. It's generally considered suited to intermediate keepers who have some grounding in water quality and flow management.

關於開腦珊瑚
Open Brain Coral (Trachyphyllia) is a flower-like LPS coral prized for its fleshy, colorful body and strong feeding response. An intermediate-level species with over a decade of potential lifespan.
迎接開腦珊瑚前需要了解的7件事
1Keep it on the sand bed
Open Brain Coral isn't attached to rock — it's typically rested on the sand bed or nestled among live rock. Arrange your layout carefully so it doesn't get rolled around by water flow.
2Provide gentle water flow
Excessive flow can damage the fleshy tissue or cause the coral to stay contracted. Aim for indirect, gentle currents that let the polyps fully expand.
3Responds well to feeding
This coral is known for its strong feeding response, often opening its mouth wide when food is nearby. Regular feeding plays a key role in keeping it healthy.
4Needs both light and feeding
Beyond photosynthesis from its symbiotic algae, this coral also needs regular direct feeding. Balancing both — not relying on just one — is key to long-term success.
5Keep distance from other corals
Its tentacles extend considerably, and contact with neighboring corals can cause stinging conflicts. Give it plenty of open space when placing it in your tank.
6Suited to intermediate keepers
This coral is generally considered an intermediate-level species. Having some experience managing water quality and flow conditions helps ensure stable, long-term care.
7Not subject to CITES
Open Brain Coral is not subject to CITES. There's no need to worry about special procedures when bringing one home.

- A.With proper care, it can live for over a decade. Maintaining both photosynthesis (via lighting) and regular feeding is key to supporting it long-term.
- Q.Is feeding really necessary?
- A.Yes, regular feeding is essential alongside photosynthesis. It responds very well to food, and you can often watch it open its mouth to capture it.
- Q.Can it be kept near other corals?
- A.Since its tentacles extend quite far, it's important to keep enough distance from neighboring corals to avoid contact. Allow extra space when planning your layout.
- Q.Are there legal procedures required to bring one home?
