The Brain Coral features florescent lime green concave holes surrounded by bright red meaty border. The Lime Green Favia Brain Coral can be aggressive towards other corals and therefore keeping it at distant place is recommended. Under actinic lighting this coral stands out from the rest and the green centers really pop out, which makes it a captivating addition to any aquarist?s tank. Due to its hardy skeleton, it is easy to maintain and that makes the Lime Green Favia Brain Coral a popular choice amongst the beginner aquarists and expert aquarist, as well as a valuable addition to any reef tank. The Lime Green Favia Brain Coral is photosynthetic in nature and manufactures food and energy using the zooxanthellae that dwells inside its tissue. It is possible to grow in a tank, and therefore makes a very good addition to any saltwaterfish aquarium. The Lime Green Favia Brain Coral thrives well in temperature range of 72-78 degrees Fahrenheit, and pH of 8.10-8.40. ˙Additional traces of calcium and strontium work wonders to the growth of this coral, and hence it is advised to be added. ˙The Lime Green Favia Brain Coral resembles a brain, due to the presence of crevices and ridges. Keep the Lime Green Favia Brain Coral away from neighboring corals to avoid the stinging behavior, because it may sting them. It will benefit from weekly phytoplankton feedings and baby brine shrimp for its continued good health.
Corals are part of a biological group known as Cnidaria. Most Cnidaria have a mouth, or mouths, that opens into one big body cavity. Due to the lack of a true digestive system, this cavity acts in its place and after the food is broken down the nutrients are then sent through the rest of the body as food. There is also no excretory system; therefore the waste is sent back through the mouth or secreted into the surrounding water.Tentacles of varying size will usually surround the mouth of Cnidaria. Most Cnidaria have tentacles with stinging cells that can shoot tiny poison darts into their prey or can even be used as a defense mechanism. Some corals lack tentacles and instead cover themselves with a thin layer of mucus and use that to collect bacteria and plankton as food. Some corals even use both of these methods. Cnidaria can either be an individual animal or members of a complex colony. These "Colony Corals" share the food and nutrients taken in by each individual.Corals have tiny living organisms that actually live in their tissue. These are called zooxanthellae and they are the reason why such strong lighting is needed in the saltwater aquarium. These algae-like creatures provide the coral with oxygen and other nutrients that are produced during photosynthesis. During this process, the zooxanthellae take up carbon dioxide and provide nutrients to the coral.Corals can use two different types of defense mechanisms. One of which is a sweeper tentacle wherein the coral reaches its tentacles out to try to damage another coral with nematocysts. The other is when the coral releases a minute amount of toxin into the water to poison another coral within certain proximity. Most "Hard Corals" should not be placed within reach of another coral.
