Feeding depends on how much light it gets, as it uses light through symbiotic algae and also catches plankton. Furry Diary's starting plan suggests feeding depends on species, many feed from the light and the water, so offer small target feedings a few times a week if you like. For exact amounts, check the food label and ask your vet or a good reef keeper.12 Furry Diary terv

It eats plankton caught by its tentacles and can be target-fed with phytoplankton or zooplankton foods placed directly on the polyps. It should never eat meaty foods meant for fish or anything not designed for corals, as that could harm it. Stick to coral-specific foods and ask your vet if unsure.12

It is a colonial coral that grows by budding new polyps, so give it room to expand on a low rock or sand bed. A little space from neighbouring corals is sensible because its tentacles carry stinging cells. In an established reef aquarium, place it low down with low to moderate current.123

It needs an established reef aquarium at about 24-27 C (75-80 F), with low to moderate light and low to moderate current. Keep water chemistry stable, with pH around 8.2-8.6, alkalinity 7-12 dKH, and calcium 400-450 ppm. Furry Diary's plan includes weekly salinity checks and water tests, plus daily top-ups with fresh RO water.13 Furry Diary terv

Clean its home by doing a water change about every 14 days, replacing 10 to 20% of the water, and top up evaporation daily with fresh RO water. Check salinity and water chemistry weekly, and inspect the light monthly. This keeps the environment stable and healthy for the coral. Furry Diary terv

Yes, it can live with other corals, but give it a little space from neighbours because its tentacles have stinging cells for catching food. It needs no companions itself, as new polyps bud off to form a colony. Place it low down to avoid conflicts with more aggressive corals.1

With stable water chemistry and proper care, it can live for many years, as it is a hardy large-polyp stony coral. Its lifespan depends on tank conditions, so keep water quality consistent. Ask a good reef keeper or vet for specific longevity expectations.13

It is best not to handle it directly, as its tentacles carry stinging cells that can irritate skin. If you must move it, use gloves or a tool and handle the stony base gently. Always wash your hands after working in the tank.1
