The Bubble Coral definitely makes a valuable addition and also an eye-catcher to any aquarium. It is topped with oddly-shaped, swollen vesicles that give it a unique appearance. Although the Bubble Coral is aggressive, it makes a great choice for any aquarium as they are hardy and has the ability to live under a relatively broad range of conditions. The Bubble Coral needs a moderately lit place where it undergoes photosynthesis with the help of the entrapped symbiotic algae, zooxanthellae. This alga manufactures food and provides nutrition to the coral using the light energy. Also, it can be fed with small pea-sized bits of fresh fish or a smattering of defrosted frozen Mysis shrimp once a week to stimulate the tentacles for feeding, but avoid over feeding. The bubbles of the Bubble Coral are specialized tentacles that regulate the amount of light, which the algae receive, by expanding or contracting their surface area. These bubbles, armed with stinging cell called as sweeper tentacles, are typically filled with water, which expands during the day, and then deflates and retracts into the skeleton when not needed. The Bubble Coral shows asexual reproduction where small growth arises from the lower edge of the flesh. This growth increases with time and eventually develops a small skeleton of its own, hence breeding in captivity is quite possible in the tank. Even by clipping off the buds manually and placing them in an appropriate location can speed up the whole process. Due to its aggressive behavior, it is suggested to provide them their own niche and keep it away from neighboring corals. Also, if any damage is caused by crabs, shrimps or other fishes, it should be immediately attended because it can cause a ?brown jelly? infection which can spread to other corals.
