Leathers & Soft Coral

Each polyp is connected by a flexible mat which is red to dark purple if Pachyclavularia sp. and lighter purple if Briareum sp. The mat may adhere strongly to rock or even a smooth surface like glass or plastic, but can also grow across the sand. Its growth rate may be very fast, and if placed too close to another coral it may grow right over it. Plenty of space should be provided to accommodate this future growth. If disturbed this coral may completely retract its polyps into the mat. Briareum sp. may occasionally shed a waxy sheet, which is a natural cleansing behavior. These corals receive most of their energy by utilizing the photosynthetic algae contained within their tissues. They will also benefit from occasional feedings of fine zooplankton. Being highly adaptable and nearly pest and disease free makes them a great choice for beginners. Most coral eating fish will not touch them; any damage that may occur to the colony is typically re-grown with vigor. They may be sensitive to the aluminum oxide in some phosphate-absorbing media, and to the over use of iodine. Occasionally blowing the colony with a baster or powerhead will help clear detritus from between the polyps and discourage nuisance algae.Star Polyp resembles its close relative Pipe Organ coral; the main difference is speed of growth. While Star Polyp grows very quickly, Pipe Organ grows much slower as it must construct a rigid tube for each polyp. Difficulty: Easy Growth Speed: Fast Lighting: Low - High Average Placement: Low - Top Water Flow: Low - Strong Temperament: Peaceful Green Star Polyp is an all-time favorite which nearly every aquarist keeps at one time or another. It is affectionately known as “GSP” and is known for its intense emerald color, which fluoresces vividly under actinic lighting. The base of each tentacle is often deep pink, with a spot of stark white in the center of each polyp.

Xenia corals do not possess stinging cells or even a full digestive system, relying heavily on dissolved nutrients in the water. Often times new aquariums (under 1 year) and those with high fish loads or frequent feedings provide the best conditions. It also contains photosynthetic algae within its tissues. Colonies may grow and divide by fission, as often as every 2 weeks. The animal may crawl over surfaces with its base, or let go completely and float to a new location. It prefers to attach to rocks or glass in a vertical position, but may grow nearly anywhere.Its pulsing behavior is not fully understood; colonies may pulse rapidly or cease completely, only to begin again later when conditions suit it. The movement may be based on feeding or respiration, as the coral lacks the fully functioning ciliary action that many other corals possess.While Xenia corals have non-stinging tentacles, it is possible for them to release potent chemicals into the water which adversely affect the growth of stony corals; the use of carbon filtration (changed frequently) and regular water changes can minimize this. It has few pests aside from syllid worms. We recommend every coral be dipped before being placed in a display aquarium.Pumping Xenia, or Pulsing coral, is a popular choice for new aquarists. Its charming appearance is enhanced by its mysterious habit of rhythmically pulsing its polyps, adding a delightful element to the reef. Its stalk is typically a light tan color with darker “feathers” on its polyps, which are held on branches which may be long or stout.
