TSA Treasure Island Leptoseris Coral

Aquacultured Leptoseris Coral

Leptoseris corals (Leptoseris spp.) are small polyp stony (SPS) corals admired for their intricate plating or encrusting growth and subtle yet striking coloration, often in shades of green, orange, and yellow. Their layered plates catch the light and add a sculptural element to the aquascape. Our leptoseris for sale is propagated from mother colonies in our aquaculture systems.

A leptoseris coral may look delicate, but it is surprisingly resilient when given stable water parameters and proper care. With moderate care requirements, Leptoseris are a rewarding step up for reef keepers ready to move beyond beginner-friendly species.

In the wild, Leptoseris are found throughout the tropical Indo-Pacific, including Indonesia and the Central Pacific. They often inhabit deeper reef slopes and shaded areas where light levels are lower and flow is calm to moderate, growing on rock ledges and vertical walls as they encrust or plate outward into broad, overlapping structures.

Leptoseris Care at a Glance

Water Chemistry for Leptoseris

Consistency is key. Stable, balanced parameters preserve color, support healthy skeletal growth, and reduce stress. Test regularly and supplement as needed to keep calcium, alkalinity, and magnesium within range.

Lighting Your Leptoseris

Reflecting their deeper, shaded habitat, Leptoseris do best under low to moderate light in the 50–100 PAR range. Look for gently filtered or indirect light, such as a partially shaded rock ledge or the middle to lower sections of the tank. If you are moving a frag to a new system or stronger lighting, acclimate it gradually over 2–3 weeks to prevent stress or bleaching. We grow our Leptoseris under EcoTech Marine Radions, metal halides, and T5 systems calibrated for gentle, balanced illumination.

Water Flow

Low to moderate, indirect flow keeps the plates clear of debris without subjecting the tissue to overly forceful currents. You want enough movement to stop detritus from settling, but not so much that the coral shows tissue recession. We use EcoTech Marine MP pumps and Reef Octopus OCTO Pulse units to create randomized flow that encourages Leptoseris to encrust and plate out evenly.

What We Feed Our Leptoseris

Leptoseris are opportunistic feeders that combine light-driven energy from their zooxanthellae with supplemental nutrition. Extra food enhances growth and coloration. Our routine includes:

• Phytoplankton: Tisochrysis, Rhodomonas, and Tetraselmis
• Fine-particle coral foods: Reef Roids and Benepets

Target the coral's surface with a turkey baster or syringe, ideally in the evening when it is more receptive, and stop water movement for about 10–15 minutes so the coral has time to capture and absorb the food.

Coloration and Tank Maturity

Leptoseris colors range from greens, oranges, and yellows to occasional more exotic hues, and holding those pigments depends on stable chemistry, balanced lighting, and regular feeding. They can adapt to systems that are not fully mature, but a more established aquarium offers greater stability and makes it easier for them to show their best color. Once settled, they steadily encrust or plate out, and consistent calcium and alkalinity support healthy skeletal development.

Common Leptoseris Challenges

• Tissue recession: poor water quality, sudden parameter swings, or excessive flow; monitor chemistry and keep flow gentle and consistent
• Bleaching: sudden changes in light intensity or prolonged exposure to overly bright light; acclimate gradually
• Debris accumulation: plating and encrusting forms can trap detritus when flow is too weak
• Pest infestations: flatworms and other parasites can target SPS corals; inspect regularly and use dips and quarantine when possible
• Slow recovery after damage: cuts or scrapes heal slowly; stable water and targeted feeding support tissue regeneration

How We Farm Our Leptoseris Frags

We start with robust mother colonies selected for notable coloration, healthy tissue, and consistent growth. Our team cuts them into frags with coral band saws for clean, smooth edges that promote recovery, then mounts each frag on a plug or small piece of reef-safe material with underwater adhesive. During healing, we feed frequently with phytoplankton and fine-particle coral diets and closely monitor alkalinity, calcium, and magnesium to minimize stress.

How to Acclimate a Leptoseris Frag

1. Temperature: float the bag in your aquarium for 15–20 minutes to equalize temperature.
2. Drip acclimation: optional but beneficial; use a slow drip over 30–45 minutes to adjust the coral to differences in salinity and chemistry.
3. Lighting: start in a dimmer area of the tank, or use a light-diffusing screen, and increase exposure over 2–3 weeks.
4. Placement: secure the frag to rockwork or a stable ledge with reef-safe glue or epoxy, in gentle to moderate flow.
