Description
WYSIWYG Trachyphyllia Rainbow Open Brain is a free-living open brain coral with fleshy tissue that expands beyond its skeleton. Stable conditions, modest light, and gentle indirect flow support healthy inflation and coloration.
Open Brain Coral Care
Open brain corals respond best to stable reef conditions. Give the coral a flat, secure position where its tissue can inflate without rubbing against rock or being pressed against the skeleton by direct flow. Acclimate it gradually to the stated light range.
| Lighting | Low to Moderate — PAR 50–100. Use a shaded placement; too much light can cause bleaching or poor extension. |
|---|---|
| Flow | Low — gentle, indirect flow only; strong flow prevents proper inflation. |
| Placement | Free-living on the sandbed. Do not glue or wedge it into rockwork; allow it to rest naturally on the substrate. |
| Aggression | Low to Moderate — sweeper tentacles may extend at night; maintain 3–4 inches of space from neighboring corals. |
| Feeding | Offer appropriately sized meaty food 2–3 times weekly after feeding tentacles extend |
| Care level | Beginner–Intermediate |
| Water Parameters | Salinity 1.025–1.026 · Temperature 76–78°F · Alkalinity 8–9 dKH · Calcium 420–440 ppm · Magnesium 1300–1400 ppm |
Placement and Feeding
Keep the coral upright and clear of sharp edges. Its tissue can expand well beyond the visible skeleton, so allow open space and prevent sand, detritus, or neighboring corals from contacting the inflated polyp.
Turn down nearby flow during target feeding, remove uneaten food, and make lighting or placement changes gradually. Stable alkalinity and salinity are more important than frequent adjustments.
