Favia are a genus of reef-building stony corals, known for their massive or thickly encrusting colonies, often dome-shaped or flat. They are commonly referred to as brain corals or closed brain corals, and are part of the family Mussidae. Favia corals are characterized by having individual walls for each corallite, and they have sweeper tentacles which can extend and sting other corals.
Here's a more detailed description:
Growth Form:
Favia corals can grow in various shapes, including massive, dome-shaped, or encrusting.
Corallites:
The corallites, which are the individual cups where the polyps live, are plocoid (placing them in a cone shape) and often have their own walls.
Septa and Costae:
These structures are well-developed and covered with fine teeth, contributing to the coral's intricate structure.
Polyps:
Favia polyps extend and feed at night, using their tentacles to capture prey and assess their surroundings.
Sweeper Tentacles:
These tentacles are used to "sweep" the water and detect nearby corals, potentially leading to aggression and "coral wars".
Habitat:
Favia corals are found in various reef environments, including shallow water and deeper slopes.
Color:
They can display a wide range of colors, including pale grey, green, brown, and often have calices of contrasting colors
Leptastrea is a genus of stony corals, often described as "encrusting" or "plocoid," meaning they grow in a flat, dome-like shape by covering the substrate. They are relatively beginner-friendly corals, known for their diverse color variations and a tendency towards slower growth compared to some other encrusting corals. Leptastrea colonies typically have small, barrel-shaped corallites with distinct grooves and tubercles.
Key features of Leptastrea corals:
Growth Form: Encrusting or plocoid, forming flat or dome-shaped colonies.
Corallites: Small, barrel-shaped corallites with grooves and tubercles separating them.
Color: Available in a wide range of colors, including cream, green, yellow, and variations of these.
Growth Rate: Generally slow-growing, making them suitable for smaller tanks or aquascapes where rapid growth is undesirable.
Lighting: Can tolerate a range of lighting conditions, from lower to moderate.
Current: Often found in areas with moderate to high water movement.
Care: Considered beginner-friendly, but proper feeding (small food particles) and adequate water parameters are important.
Stinging: Leptastrea have a stinging power, so spacing them appropriately from other corals is recommended.
Lithophyllon is a genus of stony corals belonging to the family Fungiidae, also known as mushroom corals. They are encrusting corals that can grow as colonies, though they are now more commonly found as solitary polyps. Lithophyllon are typically found in shallow reef environments and are considered uncommon.
Key Characteristics:
Colony Formation: Lithophyllon can form colonies, with some species having a central corallite distinguishable in smaller colonies.
Appearance: They are often tan in color and can resemble other corals like Cantharellus jebbi.
Habitat: They inhabit shallow reef environments.
Tentacles: Their tentacles are usually extended only at night.
Species:
Lithophyllon repanda (Oval mushroom coral), Lithophyllon undulatum (Stone leaf coral), Lithophyllon ranjithi, and Lithophyllon lobata.
Cycloseris tenuis, вид корал, се характеризира с кръгли, тънки и плоски полипи с малък централен купол. . Преградите са в значително различен ред, но всяка преграда е еднаква по цялата си дължина. Долната повърхност на полипа показва дебели, неправилно разположени ребра. Цветът му обикновено е бледокафяв или жълт. Този вид се среща в меки междурифови субстрати и се счита за рядък. Може да се обърка с Cycloseris costulata, който има по-тънки, по-правилни ребра.

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
