When you start exploring soft corals for your aquarium, one group that often comes up is leather corals. These fascinating creatures are loved by both beginners and experienced reef keepers. They are hardy, visually appealing, and add movement and character to a tank. But not all leather corals are the same. There are several types of leather coral, each with its own appearance, behavior, and care requirements.
In this guide, we will explore the most popular types of leather coral, their unique traits, and how to care for them in a reef aquarium. By the end, you’ll understand which varieties might suit your setup best and how to keep them thriving.
What Are Leather Corals?
Leather corals belong to the family Alcyoniidae and are classified as soft corals. Unlike stony corals, they do not build a hard calcium carbonate skeleton. Instead, they have a rubbery or leathery texture, which is how they got their name. Their structure is supported by tiny calcium-like spicules that provide rigidity while allowing flexibility.
Most leather corals host symbiotic algae called zooxanthellae. These algae perform photosynthesis, providing the coral with nutrients. In return, the coral offers shelter and access to sunlight. This relationship makes leather corals less demanding when it comes to feeding, as they can thrive under proper lighting.
Leather corals also play an important role in reef aquariums. They are known for their ability to release certain chemicals, a process called allelopathy, which can affect neighboring corals. While this helps them compete in the wild, in a closed tank environment it requires careful placement and good water filtration.
Why Leather Corals Are Popular in Reef Aquariums
Many reef keepers choose leather corals for several reasons. They are relatively easy to care for, making them suitable for beginners. They adapt well to different water conditions and are more forgiving than many hard corals. Their soft flowing movements add natural beauty, and their wide range of shapes and colors provide variety in aquascaping.
Another reason is their resilience. Leather corals can tolerate fluctuations in water parameters better than delicate species. They are also known for their ability to shed a waxy layer periodically, which helps them remove algae or debris from their surface. This process can sometimes alarm new aquarists, but it is completely natural and a sign of their self-maintenance.
Now, let’s look closely at the main types of leather coral that you are most likely to encounter.
Common Types of Leather Coral
Toadstool Leather Coral (Sarcophyton spp.)
Perhaps the most iconic leather coral is the toadstool. It features a broad, mushroom-like cap with polyps that extend when open. These polyps sway gracefully in the current, adding life and motion to the tank.
Toadstool leather corals come in different colors, including brown, green, yellow, and cream. Some even glow under blue lighting, making them a striking addition to reef tanks.
Care is straightforward. They prefer moderate to strong lighting and moderate water flow. Their size can vary greatly, from a few inches across to over a foot in diameter. Because of their chemical defenses, they should be given space from more delicate corals.
Finger Leather Coral (Sinularia spp.)
Finger leather corals are named for their branching, finger-like projections. These branches often extend upward and sway in the water, creating a natural reef look. They can grow quite large and are usually shades of brown or green.
They are hardy and tolerate a wide range of conditions, making them great for beginners. Finger leathers benefit from moderate to high lighting and water movement. They are also fast growers, which makes them useful for filling in empty areas of a reef tank.
Colt Coral (Cladiella spp.)
Colt corals are sometimes confused with finger leathers because of their branching structure. However, their branches are usually thicker and more fleshy, giving them a softer appearance. They have a pulsing movement that adds rhythm to the aquarium.
They are known for their fast growth and adaptability. Colt corals thrive in moderate lighting and moderate flow. Because of their rapid growth, they may need trimming to prevent them from overshadowing other corals.
Kenya Tree Coral (Capnella spp.)
Kenya tree corals are another beginner-friendly leather coral. They resemble small trees, with a central stalk and branches covered in polyps. Their soft tissue allows them to sway beautifully in the water.
One thing to note about Kenya tree corals is their tendency to drop branches, which then attach themselves elsewhere in the tank. This natural propagation can be an advantage for spreading coral across the reef, but it can also lead to overcrowding if not managed.
Devil’s Hand Coral (Lobophytum spp.)
Devil’s hand corals are easily recognized by their hand-like lobes. These lobes can vary in size and shape, giving them a unique and sometimes dramatic appearance. Their polyps extend from the surface, adding to their textured look.
They prefer moderate light and flow. Like other leather corals, they occasionally shed their outer layer, which helps them stay clean. Because of their potential size and chemical output, they should be given enough space in the aquarium.
Cabbage Leather Coral (Sinularia dura)
Cabbage leather corals form dense, folded structures that resemble leafy cabbage. They are more rigid compared to other leathers and usually grow in thick clusters. Their unique texture makes them stand out in a reef tank.
They do well in moderate light and water flow. They are hardy and suitable for beginners, but because they are dense growers, they need space to prevent competition with neighboring corals.
Umbrella Leather Coral
Umbrella leathers look similar to toadstools but have broader, flatter caps. Their polyps extend from the surface, creating a flowing effect. They can grow quite large and make a bold centerpiece in an aquarium.
These corals need strong lighting and water flow to maintain health. They may retract their polyps for days when shedding, so patience is needed during this phase.
How to Care for Leather Corals
Caring for different types of leather coral follows similar principles. Good water quality is essential. Aim for stable parameters with a temperature of 24–27°C (75–80°F), salinity around 1.024–1.026, and pH between 8.1–8.4.
Lighting is crucial because leather corals rely heavily on photosynthesis. Most species thrive under moderate to strong lighting. LED reef lights are a popular choice because they allow spectrum adjustments.
Water flow should be moderate to strong, depending on the species. Flow helps them remove debris and supports their natural shedding process. Avoid placing them in areas with no movement, as this can lead to algae buildup.
Feeding is generally optional, but occasional target feeding with phytoplankton or liquid coral food can enhance growth. Since they already obtain energy from their symbiotic algae, feeding should be supplemental rather than primary.
Placement in the tank matters. Leather corals should not be placed too close to sensitive stony corals due to their allelopathic chemicals. Using activated carbon and ensuring proper filtration can reduce these chemical effects.
Leather Coral Behavior and Growth
One fascinating aspect of leather corals is their shedding process. From time to time, they will close up and develop a shiny, waxy coating. During this stage, they may look unhealthy, but within a few days, they will shed the layer and reopen with vibrant polyps. This natural cycle helps them stay clean and free of pests or algae.
Growth rates vary among species. Fast growers like Kenya tree and colt coral can quickly spread, while larger species like toadstools may take longer to reach full size. Propagation is easy for most leather corals. Fragging, or cutting small pieces to grow new colonies, is a common practice among reef hobbyists.
Challenges in Keeping Leather Corals
Although they are hardy, leather corals still come with challenges. The main concern is chemical warfare. Their allelopathic behavior can stunt the growth of neighboring corals, particularly SPS corals. Running carbon and ensuring good water changes can minimize this issue.
Another challenge is overgrowth. Some types, such as Kenya tree or colt coral, can multiply quickly and take over a tank. Regular pruning or fragging helps manage their spread.
Lighting and flow adjustments may also be necessary as they grow. A coral that thrives in one spot may outgrow it, requiring relocation for continued health.
Final Thoughts on Types of Leather Coral
Leather corals are an excellent choice for reef aquariums, offering beauty, resilience, and variety. From the iconic toadstool to the branching Kenya tree, each type has unique traits that can enhance the look of your tank. Their ease of care makes them perfect for beginners, while their striking forms keep even advanced aquarists interested.
By understanding the different types of leather coral and their needs, you can create a thriving reef environment that highlights their natural beauty. Whether you want a centerpiece coral like the umbrella leather or fast-growing fillers like colt coral, there is a leather coral that will fit perfectly into your setup.
