The Chalice Frag is a colorful coral with a heavy tissue over its skeleton. The heavily-tissued, fleshy body adds amazing texture, and makes it a beautiful addition to any tank. The Chalice Frag is very easy to maintain, therefore it makes a very good choice for a beginner aquarist. Being a hardy species, it can be grown in almost any type of light environment. The Chalice Frag grows best with brightest colors under moderate to high light. It features long sweeper tentacles that can sting the neighboring corals, therefore keeping the other corals at a distance is recommended. The Chalice Frag should be placed horizontally in areas of low to medium and water movement. It is known to have the habit of encrusting when placed near other species in an aquarium a well as a plating habit when housed in an open areas. The Chalice Frag is nocturnal, and feeds at night. It benefits from small pieces of meaty marine foods, such as baby brine shrimp, Cyclop-eeze, or foods designed for filter feeding invertebrates. Addition supplements of calcium, strontium, and other trace element to the water column is also beneficial for its continued good health. The Chalice Frag thrives well in a temperature range of 72-78 degree Fahrenheit, and pH of 8.1-8.4.
The Green Chalice Coral is not only one of the easiest to keep, but is also very colorful. If the edge of the coral is placed against any surface, like the glass of the aquarium, or a rock it will actually encrust onto it. Green Chalice Coral is an encrusting coral and has knobby centers. They form circular formations, along with tiers. The outer perimeter of the coral, is where all the growth takes place, is very delicate. They can be mottled in a few or several colors, including green, red, brown, pink, purple, and blue with a green oral disc. 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.
