Emerald Galaxea Live Aquaculture LPS Coral

from $32.95

Emerald Galaxea Coral – Premium LPS-Style Stony Coral | coralSLover®

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.

Scientific Insight:
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.

Care & Placement:

  • Lighting: Moderate to high

  • Flow: Moderate, allowing tentacles to extend naturally

  • Placement: Ideal on rock surfaces or reef slopes, allowing space for sweeper tentacles

Why Choose Emerald Galaxea:

  • Premium Aquaculture Coral: Sustainably grown by coralSLover®; never wild-collected

  • Vibrant Display: Fluorescent tentacles create a striking visual contrast

  • Dynamic Interaction: Sweeper tentacles provide natural movement and reef realism

  • Long-Term Stability: Proven resilient to varied water parameters

Great For: Reef hobbyists and aquarists looking for a visually impressive, long-term centerpiece coral that combines color, texture, and natural movement.

Sustainability & Provenance:
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.
