Essential Care Guide for Leather Corals in Your Reef Aquarium for Optimal Growth and Health

Leather corals are a popular choice for reef aquarium enthusiasts due to their unique texture, vibrant colors, and relative hardiness. With over 20 years of experience in reef tank keeping, I’ve seen firsthand how proper care can help these corals thrive and add dynamic movement to your underwater landscape. This guide will walk you through everything you need to know to maintain healthy leather corals, from lighting and water parameters to feeding and placement.
Once a mainstay of every reef tank - with advances in Care of SPS and LPS corals the humble leather coral has fallen somewhat out of fashion.
Understanding Leather Corals care
Leather corals belong to the family Alcyoniidae and are soft corals known for their flexible, leathery texture. Unlike stony corals, they do not build hard calcium carbonate skeletons, which makes them easier to care for in many reef setups. They come in various shapes and sizes, including finger-like projections, broad plates, or tree-like branches.
These corals rely heavily on photosynthesis through their symbiotic zooxanthellae algae, which means lighting plays a crucial role in their health. They also benefit from occasional supplemental feeding, although they can survive primarily on light and dissolved nutrients.
Lighting Requirements for leather coral care
Leather corals thrive under moderate to high lighting conditions. In reef aquariums, LED or T5 fluorescent lights that provide a full spectrum are ideal. Here are some tips for lighting:
Intensity: Aim for 100 to 250 PAR (Photosynthetically Active Radiation) depending on the species.
Duration: Provide 8 to 10 hours of light daily to mimic natural daylight cycles.
Placement: Start with the coral placed mid-level in the tank. If it shows signs of bleaching or shrinking, adjust the position lower or higher accordingly.
Proper lighting encourages polyp extension and vibrant coloration, which are signs of a healthy leather coral.
Water Parameters for Leather Corals care
Maintaining stable water conditions is essential for leather coral health. These corals are moderately tolerant but still require consistent parameters:
Temperature: 75°F to 82°F (24°C to 28°C)
Salinity: 1.023 to 1.025 specific gravity
pH: 8.1 to 8.4
Alkalinity: 8 to 12 dKH
Calcium: 400 to 450 ppm
Magnesium: 1250 to 1350 ppm
Nitrate: Below 10 ppm
Phosphate: Below 0.03 ppm
Regular testing and water changes help maintain these levels. Leather corals can tolerate slight fluctuations but prolonged instability will stress them and reduce growth.
Water Flow Needs for leather coral care
Leather corals prefer moderate water flow. Too little flow can cause detritus buildup on their surface, leading to tissue damage or algae growth. Too strong a current can cause the coral to retract and lose its shape.
Ideal flow: Gentle to moderate, enough to sway the coral but not flatten it.
Placement: Position near powerheads or wavemakers that create indirect flow.
Observation: Watch for polyp extension and movement; these indicate comfortable flow conditions.
Feeding Leather Corals
While leather corals get most of their energy from photosynthesis, they also benefit from supplemental feeding. Feeding encourages faster growth and enhances coloration.
Food types: Phytoplankton, marine snow, and finely chopped meaty foods like brine shrimp.
Frequency: Feed once or twice a week.
Method: Use a turkey baster or pipette to gently deliver food near the coral’s polyps during feeding times.
Avoid overfeeding, which can degrade water quality and harm the coral.
Placement and Tank Mates for leather corals
Choosing the right location and neighbors in your reef tank is critical for leather coral success.
Placement: Mid to upper levels of the tank with moderate light and flow.
Space: Leave room around the coral to prevent aggression or overgrowth from neighboring corals.
Tank mates: Compatible with most reef-safe fish and invertebrates. Avoid species known to nip or damage soft corals, such as certain angelfish or butterflyfish.
Chemical warfare Some leathers will release toxins to prohibit growth of encroaching corals - these can be particularly harmful to delicate SPS/LPS - so be sure to run plenty of activated carbon to reduce build up.
Leather corals can sometimes release chemical compounds that inhibit other corals. Using activated carbon in your filtration system helps reduce this effect.
Common Problems and Troubleshooting leather coral care
Even with proper care, leather corals can face issues. Here are common problems and solutions:
Mucus shedding This is a normal action by most leathers they'll close right up for a day or two and then shed off there waxy mucus, if the coral remains closed or sheds very frequently it can be a sign of distress - poor water quality or pest irritation.
Bleaching: Usually caused by excessive light or temperature stress. Move coral to lower light or stabilize temperature.
Tissue recession: Often due to poor water quality or pests. Check water parameters and inspect for flatworms or nudibranchs.
Brown jelly disease: A bacterial infection that causes tissue to turn brown and slough off. Remove affected parts and improve water quality immediately.
Algae overgrowth: Caused by excess nutrients and low flow. Increase water flow and reduce feeding.
Regular observation helps catch problems early before they become severe.
Propagation and Growth Tips for leather coral care
Leather corals are relatively easy to propagate, making them a favorite for hobbyists who want to expand their collection or share with others.
Method: Use a sharp, clean blade to cut a healthy branch or section.
Healing: Attach the frag to a rock or frag plug using rubber bands or coral glue.
Conditions: Keep frags in moderate light and flow until they show new growth.
Growth rate: With good care, leather corals can grow several inches per month.
Patience is key, as growth rates vary by species and tank conditions.
