Brain corals are carnivorous and will eat a variety of marine foods, including meaty marine flesh, zooplankton-based foods, Mysid shrimp, krill, and baby brine shrimp. You can also try commercial foods such as Cyclop-eeze, a liquid invertebrate feeder. You can try any of these foods if you want to try a new species.

Trachyphyllia geoffroyi
Open Brain Coral feeds by extending its feeding tentacles from its fringe around its oral disc. These corals prefer feeding on krill or similar sized marine foods. Unlike many corals, however, they will require additional food in order to thrive. In addition, they tend to produce excessive waste and will need to be targeted-fed several times a week. If you plan to feed your Open Brain Coral, be sure to switch off all of your aquarium’s equipment prior to feeding.
If you keep Trachyphyllia in a tank with too much water flow, it will likely be bleached and require some treatment. Once it’s bleached, it will take a long time to recover and will eventually change color. You can prevent this from happening by aggressively feeding your corals and introducing them to a nutrient-rich water column.
Planulae
The planulae, or larvae, of the brain coral are the main sources of food for the animals. This echinoderm forms when the sperm and egg meet and attach to the surface. These animals feed on algae and other organisms, but they also produce a toxin, Palytoxin, which can be fatal for humans. It’s important to avoid eating these animals.
This larval stage of Hydractinia echinata begins as an asexual polyp, but can develop into a medusoid colony. These planulae develop from fertilization and attach to a solid surface by using their cilia. The medusoid stage of their lifecycle is responsible for the development of the colony. The colony is a succession of new polyps. The old polyps die, but their skeletons remain.
The reproductive cycle of the brain coral is complex. It involves the release of gametes by the colony. These gametes fertilize the egg. Eventually, the egg-containing polyps release larvae into the water column. Asexual reproduction of planulae occurs when coral polyps spawn, but it also occurs when male and female polyps mate. Then, the eggs and larvae hatch, and the coral colonies begin to form new colonies.
Mussidae
Mussidae are a family of Tethyan corals. Most genera are extant, and have clear morphological affinities with the Meandrinidae. Their colonies are usually solitary and their skeleton structures are solid. The corallites are very large. Mussids have large lobes and teeth on their septa, and are considered particularly hardy.
Mussidae are a small family with thirteen genera, including Scolymia and Mussa. The genus is widely distributed, although four genera are only found in the Atlantic and Indo-Pacific. They are similar in size to pectiniid corals, with a large, robust skeleton, and a large number of septa. Despite the family’s small size, Mussidae corals are excellent sources of calcium and magnesium for reef-building.
A great source of calcium carbonate is the muscle tissue found inside brain corals. Scientists have even used this calcium carbonate exoskeleton to study the strength of the grips on wheels. Mussidae are among the most important reef builders and are found in many shallow oceans. They are a food source for other coral species in the Mussidae family, as well as other stony corals.
Merulinidae
If you’re a serious reef aquarium hobbyist, you’re looking for a brain coral food that will keep your meds looking vibrant and healthy. Merulinidae brain corals feed primarily at night and take out their tentacles to hunt for food. Though they are most active at night, they can acclimate to hunting during the day. It’s important to feed the same kind of food to all your corals, regardless of their stage of development.
Several types of brain corals exist, including the open and grooved varieties. The grooved variety is gray and looks like a large reef building coral, growing up to six feet in diameter. The open variety, meanwhile, is a different species that can appear in bright colors and grows on flat plates. These species prefer moderate water flow and light levels, but they can’t withstand high levels of light.
