The Trumpet Coral is a large polyp stony coral, and features branching individual stalk skeletons along with bright colored tissues at their tips. These branches goes upward from its central base forming ?trumpet? like structures, thus it is named as Trumpet Coral. The Trumpet Coral is easy to care for, and comes in hues of fluorescent green. The Trumpet Coral is also considered as Bullseye Coral due to its bizarre structure. It does not require a special place in your fish tank, and can do very well in medium light with moderate water movement. The Trumpet Coral bears short sweeper tentacles that lack the ability to sting nearby corals. The best way is to keep it at the bottom of the tank. The Trumpet Coral is mostly present in colonies and share each other?s food and nutrients. It has tiny living organisms in their tissue which are called as Zooxanthellae. This is the reason why there is need of strong lighting in an aquarium where these corals are the inhabitants. These Zooxanthellae that dwell inside its tissue, undergo photosynthesis and provide oxygen and other nutrients to the coral. The Trumpet Coral has mainly two different types of defense mechanism. One is sweeper tentacles where it reaches out to damage another coral with nematocysts. Another is when the coral releases the toxin in to the water. Although the Trumpet Coral is photosynthetic, it is still beneficial to have an addition of brine shrimp, microplankton, phytoplankton, and other filter feeding foods.
