Anthelia coral, also known as Waving Hand or Glove Coral, is a soft coral genus characterized by long, thin, and often purple or bluish polyps that wave gracefully in the current. These corals form a creeping mat, with their polyps extending from the base. They are known for their light appearance and constant movement, resembling an underwater field of seagrass.
Here's a more detailed description:
Appearance: Anthelia corals have a distinctive appearance with long, thin polyps that resemble gloves or waving hands. They often have a creeping mat base, with the polyps extending upwards.
Color: They can come in various colors, including pink, blue, brown, or tan.
Movement: The polyps of Anthelia corals wave in the water current, giving them their common name "Waving Hand Coral". They are not known for the pulsing behavior seen in Xenia corals, but rather a gentle swaying.
Growth: Anthelia corals are fast-growing and can quickly cover adjacent rock work.
Care: They are relatively easy to care for, requiring medium to high lighting and a medium to strong water flow.
Invasive: They can be a bit invasive and should be placed with plenty of space, as they may overgrow other corals.
Other names: They are also referred to as "Glove Coral," "Pom-Pom Coral," or "Anthelia Waving Hand Coral".
Nutrient requirements: While they rely on symbiotic zooxanthellae for photosynthesis, trace elements like iodine are beneficial.
Anthelia corals are a popular addition to reef aquariums, adding a visually appealing and dynamic element with their waving polyps and graceful movement
Pulsing Xenia (Heteroxenia fuscescens) is a soft coral known for its rhythmic, pulsing movement and feathery polyps. It has long, sturdy stalks adorned with feathery tentacles that pulse, opening and closing in a "pumping" fashion, adding movement to the reef tank. Pulsing Xenia is a fast grower and a popular choice for reef tanks, both for beginners and experienced hobbyists.
Here's a more detailed description:

Gorgonia, or sea fans, are a genus of soft corals found in marine environments, particularly in areas with strong water currents. They are characterized by their fan-like shape and often have a purple hue, though other colors like brown or yellow can also occur. Sea fans are colonial invertebrates, meaning they are made up of many individual polyps, which are small, fragile, white "flower-like" structures.
Key Features:
Colonial Nature:
Gorgonians are colonies of polyps, which are attached to a central axis composed of gorgonin and calcite.
Fan-like Structure:
The polyps are arranged in a fan-like pattern, creating the distinctive shape of sea fans.
Color Variation:
While often purple, sea fans can also be brown, yellow, or even pink, depending on environmental factors and the presence of pigments in their spicules (needle-like parts of calcium carbonate).
Filter Feeders:
Sea fans are filter feeders, meaning they capture small particles of food from the water current using their tentacles.
Geographic Distribution:
Common sea fans (Gorgonia ventalina) are found in the Caribbean Sea and tropical western Atlantic, including areas like the Florida Keys, Cuba, Belize, and Venezuela
Briareum is a genus of soft corals in the family Briareidae.The coral is cultivated by aquarium owners (under the common name "green star polyp" or GSP) for its fluorescing polyps, which reveal themselves under actinic light. The genus is in need of extensive examination, as many specimens sold by marketers display unique and similar characteristics, but are often labeled as one species, Pachyclavularia violacea.
Green Star Polyps (GSPs), also known as Pachyclavularia violacea or Briareum, are a popular soft coral known for their vibrant green or yellowish-green tentacles and a purple or blue base. They form a mat-like colony and are generally considered easy to care for. GSPs are popular with reef aquarium enthusiasts.
Here's a more detailed description:
Appearance:
GSPs have multiple polyps attached to a rubbery, purplish-red mat. Each polyp has eight thin, smooth tentacles that can range in color from pale to fluorescent green. They often have a contrasting color (like white or yellow) at the center of the polyp.
Size:
While they can reach a colony size of up to one foot in diameter, the individual polyps are typically less than 0.5 inches across.
Behavior:
GSPs are generally open during the day and may retract their tentacles at night or when disturbed.
Habitat:
They are found in shallow to moderate depths along reef edges in the Indo-Pacific Ocean.
Diet:
GSPs are filter feeders, absorbing organic matter from the water column and also hosting zooxanthellae, which provide them with nutrients through photosynthesis.
Reproduction:
They can reproduce by forming new polyps at the edge of the mat or by brood larvae

Cladiella are a genus of soft coral belonging to the family Alcyoniidae. They are known for their distinctive finger-like projections, which can be round or cone-shaped, extending from a short stalk. These projections branch in various directions and have polyps extending from their tips. Cladiella are hardy, fast-growing corals that can grow up to 41 cm in height. They are often pale in color, with contrasting brown or greenish-brown polyps. They are also known to be slimy to the touch due to the production of mucus.
Here's a more detailed description:
Appearance:
Cladiella have a leathery, smooth base tissue, which can be pale or white, often with an orangey-pink central column. The finger-like projections are the most noticeable feature, with polyps extending from their tips.
Color:
The base tissue is typically pale or white, while the polyps can be brown or greenish due to the presence of zooxanthellae (symbiotic algae). Some species, like Cladiella australis, are known to appear brown with extended polyps but turn white when the polyps retract.
Growth:
Cladiella are relatively fast-growing corals, with some species reaching up to 41 cm in height.
Habitat:
Cladiella are commonly found in the Indo-Pacific region.
Care:
Cladiella are relatively easy to keep in a reef aquarium and are often recommended for beginners. They prefer a moderate to strong current and are adaptable to varying water parameters.
Other notable features:
They are known for their hardiness and can be found in a variety of colors, including pink, red, and purple.
Lobophytum is a genus of soft corals, also known as devil's hand or finger leather corals, found in the Indo-Pacific region. These corals are characterized by their fleshy, finger-like outgrowths forming an umbrella-like structure on a short stalk. They are often tan or purple, but can also be brightly colored.
Key features of Lobophytum corals:
Appearance:
They resemble Sarcophyton (toadstool leathers) but have thick-fleshed, finger-like outgrowths.
Distribution:
Found in shallow water throughout the tropical Indo-Pacific.
Identification:
Accurate species identification requires microscopic examination of sclerites (calcareous needles).
Care:
Lobophytum corals require moderate to high lighting to support zooxanthellae, filter-feed, and may benefit from plankton supplements.
Aggression:
They are moderately aggressive, potentially releasing a toxin that irritates other corals.
Propagation:
Lobophytum corals are known for easy propagation and "fragging".
Microbiome:
Research suggests that the soft coral microbiome is relatively resilient to short-term environmental stressors.
Lighting:
Lobophytum corals are not particularly picky about lighting, but low to moderate light is generally preferred.
Salinity:
Maintaining a salinity between 34/35 per mille (1.022 and 1.024 density) is crucial for their health.
Sarcophyton is a genus of soft corals, commonly known as toadstool or mushroom leather corals, belonging to the family Alcyoniidae. They are popular in reef aquariums and are known for their fleshy, soft, and often ruffled appearance, resembling toadstools or mushrooms.
Here's a more detailed description:
Appearance:
Sarcophyton corals typically have a stalk and a flat, often ruffled or folded cap (capitulum). They come in various colors, including brown, white, and gold.
Soft Coral:
Unlike stony corals, Sarcophyton corals lack a hard, stony skeleton. They are made of soft tissues and do not contribute to reef building.
Habitat:
They are found in various reef environments, particularly in the Indo-Pacific and tropical to subtropical climates.
Care:
They are generally considered easy to care for and can thrive in a wide range of conditions, including moderate to strong water flow and light, and can tolerate some fluctuations in water parameters.
Symbiotic Relationships:
They host symbiotic algae (zooxanthellae) that provide them with nutrients, contributing to their growth and coloration.
Growth:
Sarcophyton corals can grow rapidly, sometimes shedding some of their outer skin as they mature
