The Colt coral is a soft, branching coral that is found in Indo-Pacific coral reefs. It does not have the calcium carbonate skeleton of the reef building corals. It is a hardy aquarium species and is commonly cultured. Like other corals, its tissues are home to photosynthetic algae known as zooxanthellae which provide the coral with oxygen and nutrients.
The Red mushroom anemone is also known as Mushroom coral or Disc anemones. They can vary in shade from red to pink or purple and are a hardy aquarium species. Symbiotic algae, known as zooxanthellae, are responsible for the red color and also provide the coral with nutrients and oxygen. These corals readily reproduce in an aquarium by a cloning process known as budding.
