How to feed the Open brain coral?
Like many corals, Trachyphyllia gets part of its food from zooxanthellae. These are microscopic algae that grow directly in the coral with the help of light. Under strong light, the zooxanthellae can perfectly suffice to feed your Trachyphyllia.
If it is located in the shade, you will have to supplement its diet: once a week for a large specimen, every two weeks for smaller animals. Place a small piece of mussel or peeled shrimp near its mouth (2-3 mm / 0.08-0.12") is enough). Plankton is also recommended.
In nature, this coral feeds at night. It therefore takes out its tentacles to hunt only at night. It is therefore preferable to feed it at this time but you can acclimatize your coral little by little to hunt during the day (in this case, always offer food at the same time).

Ideal to fill your open spaces on the sand, this coral will nicely dress the bottom of your aquarium. Give it enough space to inflate at will (10 cm all around will do the trick).
Moreover, this coral when it is green or brown seems to support the light well and should be installed in a clear place, but always in the depth of the tank (average light intensity). The red or blue varieties should be placed in mid-shade, away from an overhang (low light intensity). Under blue light, they become phosphorescent!
For the current, a light gentle stirring is appreciated but never direct the current directly at it (no strong stirring that damages it).
