Common names include: sea mat and button polyps. Alcyonium are hardy corals that do well in aquariums, but should be provided with bright lighting and good water movement. Corals in this genus are slimy to touch rather than having the dry, leathery feel of most leather corals, yet they are not as sensitive to handling as many soft corals, and are easy to propagate. The term soft coral is used broadly and relatively unscientifically (is that even a word?) Filter. Palytoxin Poisoning: Marine Aquarium Safety. Secondly, hard coral polyps are built on a six-fold symmetry, while soft coral polyps are built on an eight-fold symmetry. In the past, soft corals were thought to be unable to lay new foundations for future corals, but recent findings suggest that colonies of the leather-coral genus Sinularia are able to cement sclerites and consolidate them at their base into alcyonarian spiculite, thus making them reef builders. Many of the soft corals are quite hardy and some of the easiest corals to keep. Photo courtesy Paige Gill, Florida National Marine Sanctuary. They produce a potent toxin called palytoxin. Wash your hands after handling them or working in the aquarium. Government of South Australia. Nevertheless, home-grown specimens tend to be more adaptable to aquarium life and help conserve wild reefs.

Soft Corals which are also known as Alcyonacea, is an order of corals which do not produce calcium carbonate skeletons, but instead have spiny skeletal elements called sclerites which give these corals some degree of support while giving their exterior a grainy or spike like texture that deters potential predators. These cnidarians are related to stony (scleractinian) corals, but they lack a massive, calcified skeleton and have eight hollow feather-like tentacles instead of 6 or multiples of six found in stony corals. Always handle these corals carefully, and wear gloves to protect your skin. Dr. Saint-Erne is is part of The Spruce Pets' veterinary review board. Soft Corals In reef aquariums, it is important to leave adequate space between different species of hard and soft corals to avoid problems with growth or aggression. Soft corals on the other hand are held together by a jelly-like mesoglea and rigid, spiny structures called sclerites hold together soft coral polyps. Different species of coral are found in different habitats and different locations around the world. The soft coral species listed below are good choices for any reef keeper and are ideal for beginning reef keepers to start with. They thrive in moderate lighting and water movement conditions. In our first Caribbean coral identification story, we talked about 10 common stony corals.Today we’ll cover 10 common soft corals. Requirements vary by coral species. Gorgonians possessing zooxanthellae are usually characterized by brownish polyps. Beautiful, live soft corals can be easy to take care in reef aquariums. Staghorn Coral. This particular species of coral is also known as Round Starlet coral due to … Corals are diverse groups of invertebrate animals.  The pygmy seahorse not only makes certain species of gorgonians its home, but also closely resembles its host, thus is well camouflaged. Hard corals like lobed star coral and pillar coral are reef-building corals. These corals contain zooxanthellae, but do need to be fed. Their placement in an aquarium should be considered carefully, as they will overgrow most other corals. There are approximately 6,000 species of anthozoans classified in several orders and subclasses, including hard and soft corals, sea whips, fans, antipatharians, sea pens, zooantharians and sea anemones. The suborder Scleraxonia species are supported by a skeleton of tightly grouped calcareous spicules. And since many corals derive a substantial portion of their nutrition through absorption of nutrients from the water, they actually survive in less-than-perfect water conditions. Sclerites give these corals some degree of support and give their flesh a spiky, grainy texture that deters predators. Exporter of Premium and Ultra Corals, Invertebrates and Live Rock and we are AKKII member (Indonesian Coral, Shell and fish association), and also CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) to deliver corals to all countries in America, Europe, Asia, Middle East and Africa. Tree Corals. Soft corals grow quickly in captivity and are easily divided into new individuals, and so those grown by aquaculture are often hardier and less expensive than imported corals from the wild.

Common names include: mushroom coral, and disc anemones. Palytoxin Poisoning: Marine Aquarium Safety. Soft corals (Cnidaria: Anthozoa: Octocorallia) often equal or exceed the total coverage of scleractinian corals in coral reef ecosystems –, and as dominant space-occupiers, important structural components of coral reef communities, and contributors to coral reef biomass , , have been the subjects of biological studies since the nineteenth century. Consequently not all soft corals are easy keepers. is a relatively new species of soft coral that can grow very well over rock and sand. It is very important to learn about the soft coral species you keep for a successful reef aquarium.
