Green Bubble Coral
One of the most exciting and interesting types of coral is the green bubble coral. Also called Grape Coral or Pearl Coral, they are quite popular in home reefs due to their strange, unique appearance and can be quite impressive under ideal conditions. Green Bubble Coral generally originate in the Tropical Pacific and Indian Oceans, and can almost glow under the right lighting.
Characteristics of Green Bubble Coral
Green Bubble Coral is composed of fleshy tissue residing in a protective hard skeleton, made from calcium deposits that the tissues, or polyps, secrete. This type of coral gets its name from its bulbous tentacles that are used to absorb light needed for photosynthesis. Green Bubble Coral can be many shades of green, from light lime to bold fluorescent green. The walls of this coral skeleton are surprisingly very sharp.
Green Bubble Coral Lighting
Aquarium enthusiasts love Green Bubble Coral because of their unique look. These corals will need light according to the lighting in their origin. Many specimens from the Red Sea are found in shallow, well-lit waters. These may be placed in brighter lighting after acclimation. However, green bubble coral found in other areas are often found in shaded ledges or in turbid waters, and require less lighting.
Aquarium Placement of Green Bubble Coral
At night, Green Bubble Coral extend their stinging tentacles, called sweeper tentacles, to keep other corals from growing too close. This behavior is similar to many types of herd corals. If damaged or dying tissue is noticed on bubble coral, you may need to move them further apart. Unfortunately in an aquarium setting, neighboring corals may be accidentally stung if placed too close in the tank.
Green Bubble Coral Feeding and Care
Green Bubble coral is photosynthetic, but seem to benefit more than many LPS corals from occasional direct feeding of shrimp or other meaty foods. Feeding up to once a week will result in faster growth. Calcium levels in the water are important for skeletal development. They prefer low to moderate water current for optimum health.
Green Bubble Coral Overview
Green Bubble Coral are an aquarium enthusiast favorite for their unique shape and moderate hardiness, as well as relative ease in care in a captive tank. The green bubble coral is native to the Indo Pacific region, including waters surrounding Australia, the Indian Ocean and to the Red Sea. It is quite a popular with marine aquarium enthusiasts because of its interesting look and wide array of colors and interesting textures.
