What is coral aquaculture?

Coral aquaculture is the process of growing corals in controlled environments instead of collecting them from the wild. At coralSLover®, we propagate our corals in shore-based, recirculated saltwater systems to produce healthy, vibrant, and sustainable specimens for home aquariums.

Why choose aquacultured corals over wild-collected corals?

Choosing aquacultured corals is like choosing organic produce—quality and care are prioritized over cheap, mass-produced options. Aquaculture corals are grown in controlled systems, are already adapted to aquarium conditions, and help reduce pressure on natural reefs by avoiding wild harvesting.

How are aquaculture corals more eco-friendly?

Aquaculture corals are grown without removing colonies from natural reefs. Fragments are taken from established parent colonies and grown in indoor, recirculated systems. This protects wild reef structures, reduces collection impact, and supports long-term reef conservation.

Are aquacultured corals better adapted to home aquariums?

Yes. Tank-grown corals are raised under artificial lighting, filtration, and water flow similar to home reef systems. This makes them hardier, more stable, and generally easier to acclimate than wild corals, which come from very different natural conditions.

How does coralSLover® grow aquaculture corals?

coralSLover® uses shore-based, recirculated saltwater systems to grow coral fragments from parent colonies. These systems allow precise control over lighting, water chemistry, and flow, supporting sustainable growth and consistent quality for reef aquariums.

What are the main benefits of aquacultured corals?

Aquacultured corals are eco-friendly, tank-adapted, and sustainably grown. There is no wild harvesting, helping protect natural reefs. Corals are hardier and already accustomed to aquarium life, and fragments are farmed from parent colonies using nursery-style techniques similar to how plant nurseries propagate cuttings.

Emerald Galaxea Coral – Collector-Grade LPS-Style Stony Coral | coralSLover®

Classification: coralSLover® Collector LPS Coral

Coral Type: LPS Coral
Scientific Name:Galaxea sp.
Family: Merulinidae
Category: Collector Coral
Common Names: Emerald Galaxea Coral

Why Collector Grade:
This morph is classified as Collector Grade due to its exceptional fluorescence, deep rich coloration , long tentacle extension, and proven long-term stability in aquaculture, making it a rare and refined addition to advanced reef displays.

Bring intense color and dynamic movement to your reef aquarium with the Emerald Galaxea Coral, a stunning stony coral featuring a deep green body and vivid fluorescent green tentacles. This premium LPS-style coral is prized for its visually striking appearance and hardy aquaculture growth.
Galaxea corals are known for their long sweeper tentacles, which can extend up to 2 inches and are used for territorial defense in reef environments. The tentacles host symbiotic zooxanthellae, which contribute to their vibrant fluorescent coloration and support photosynthesis. Emerald Galaxea exhibits moderate growth, encrusting over rock surfaces to form dense, textured colonies that create visual depth in reef displays. While aggressive toward neighboring corals due to their sweeper tentacles, they are resilient and adapt well to a variety of tank conditions when given stable water parameters.

Frag Size: Approximately 1.5” clusters with skeletal base 3/4" up to 1”, fully open tentacles showcase the vibrant green coloration.

This Emerald Galaxea has never been wild-collected. This strain has been part of the coralSLover® aquaculture program, originally obtained as a small frag for our private collection. Over nearly a decade of propagation, it has proven remarkably stable and resilient. By growing it entirely in our controlled systems, we ensure a healthy, acclimated coral while protecting natural reefs from collection stress.

LPS Corals – Colorful, Hardy, and Easy to Enjoy

LPS corals, or Large Polyp Stony Corals, are one of the most popular types of corals for reef aquariums. Unlike SPS corals, which have tiny polyps, LPS corals have larger, fleshy polyps that expand and move with the water, giving them a lively, flowing appearance. Their solid calcium skeletons provide structure to your reef, while their soft, colorful polyps bring vibrant color and texture that can transform a tank into a dynamic underwater garden.

LPS corals are beloved by both beginners and experienced hobbyists because they are hardy and relatively easy to care for, yet still offer striking colors and patterns. Many species, like Acan, Blastomussa, Candy Cane, Chalice, Frogspawn, Galaxea, Hammer, Lobo/Brain, and Torch, can thrive under moderate lighting and medium water flow, making them versatile for most reef setups. Their large mouths allow them to feed effectively, and occasional target feeding can encourage faster growth and more intense coloration.

At coralSLover, all our LPS corals are aquacultured, meaning they are sustainably grown in controlled systems to ensure they adapt successfully to home aquariums. This gives your reef a better chance of thriving, with healthy, vibrant corals that are easier to maintain. Whether you’re starting your first reef or adding colorful accents to an established tank, LPS corals are a favorite choice for creating movement, beauty, and life in any marine display.

Care at a Glance – LPS Corals

Lighting: Moderate to moderately high lighting brings out vibrant coloration and supports steady growth. Many LPS prefer indirect or slightly shaded areas to avoid tissue stress.

Flow: Moderate, indirect water movement is ideal. Gentle but consistent flow keeps polyps clean and extended without damaging their fleshy tissue.

Placement: Mid to lower rockwork or sandbed is often best. Allow ample space between colonies, as many LPS have long sweeper tentacles and can sting neighbors.

Water Quality: Stable parameters are key — maintain balanced alkalinity, calcium, and magnesium levels with low to moderate nutrients. Sudden changes can stress fleshy polyps.

Feeding: LPS benefit from targeted or occasional broadcast feeding of meaty or particulate foods to support faster growth and vibrant coloration.

Difficulty: Beginner to intermediate friendly — many LPS are hardy but appreciate consistent conditions and occasional feeding for best results.

Sustainability: Fully aquacultured, zero wild collection — responsibly grown and well adapted to aquarium life.
