WYSIWYG Coral
The coral pictured is the exact specimen you will receive—guaranteed. Every WYSIWYG coral is photographed individually, then carefully conditioned and monitored until shipment.
Because it remains alive and growing in our system, its size and shape may naturally develop after the photograph is taken. While it waits for its new home, we carefully maintain stable conditions to keep its coloration as true to the photograph as possible.

Theia’s Return Diaseris Care Guide
Theia’s Return Diaseris is a free-living plate coral suited to an open sand bed where its tissue cannot rub against rockwork.
- Care level
- Moderate
- Suggested PAR
- 75–150
- Water flow
- Low to moderate
- Placement
- Open sand bed
- Aggression
- Medium to high
- Feeding
- One to two times weekly
What Theia’s Return Diaseris needs
Set the coral upright on fine sand with open space around the entire rim. Rock edges can cut inflated tissue, and strong direct flow can flip smaller plates. Feed small meaty foods only when the feeding response is visible.
Stable water targets
Use these as a steady operating range, not numbers to chase from day to day.

How to acclimate Theia’s Return Diaseris
- Inspect the bag and coral on arrival. Photograph any shipping concern before opening the bag, then follow the store's live-arrival instructions.
- Match temperature, inspect the coral under white light, and use a coral dip that is appropriate for the coral group. Do not add shipping water to the display.
- Begin below the final light intensity for the first several days. Move or raise intensity gradually while watching tissue and polyp response.
Theia’s Return Diaseris care questions
Where should I place Theia’s Return Diaseris?
Start at Open sand bed. Leave room for growth and move the coral only after observing its response to the current position.
How much flow does Theia’s Return Diaseris need?
Use Low to moderate flow. The goal is steady gas exchange and debris removal without folded tissue, exposed skeleton, or polyps held in one direction.
Should I feed Theia’s Return Diaseris?
Recommended frequency: One to two times weekly. Feed only when the coral shows a response, use appropriately sized food, and remove uneaten food before it irritates the tissue.
