Galaxea corals grow well and are great if well managed. In Doc Aquarium’s reef aquarium designs we place these corals high near an overflow, on their own island in the sand or on a the top of a pinnacle away from other stony corals. They look great growing on the back wall of a reef aquarium as their sweeper tentacles sway around in the flow. They are aggressive so keep them in the down flow of other corals or near the overflow.
Care level: beginner to intermediate
Flow: medium high to medium low
PAR: 150-250, will handle up to 450nm with no issues
Original Location Range: Indonesia, Coral Triangle, South Pacific
Grown in our California coral farm providing zero impact corals
Water chemistry: Calcium 400-450, Magnesium 1350, KH 7-9.5, pH 8.1-8.4, Nitrates .01-10+, Phosphates .01-.1, salinity 1.026
Temperature Range: 74- 81 Fahrenheit
Feeding: these corals can be target or broadcast fed. They will feed on smaller soaked pellets and will do well without direct coral feedings if there is heavy fish feedings. Target feeding is always best and be sure your coral is taking in the food and not just sliming it off.

Dosing: Doc highly recommends automated dosing of Ca, Kh and other elements to provide ultimate stable water chemistry throughout the day. It is important there are no fluctuations especially with Kh/alkalinity. For more information on dosing and products click here.
In many of our custom aquarium designs, we like to plant these corals in areas with moderate flow on a stable area.
Attachment: Use disposable gloves, a small flathead sculpting tool, coral glue and coral clippers. In many of our custom aquarium builds we like to use coral glue. It is recommended to try and break off as much of the disk safe enough not to damage the skeletal branch or underside of the coral. We do this by using coral bone cutters. Add a good amount of coral glue to the underside of the coral branch. Prime the reef area you wish to place the coral by smearing the glue onto the rock. Press the coral disk onto the desired location. It does help to slightly twist, tilt back and forth the coral to help cure the glue. Press it down firmly and use your favorite sculpting tool to clean up the excess glue. Be sure the coral is fully secure, the coral should never fall off the reef. Most frags will grow quite large so be a little generous with the glue to withstand the weight of the future coral colony growth. We find it helps using only the extra thick reef glue gel. Be sure to rub a little reef glue onto the reef section and there is enough reef glue on the coral plug to set it securely.
