Rainbow Galaxea Live Aquaculture SPS Coral

from $41.95

Rainbow Galaxea – Live Aquaculture Coral
Dynamic Colors | Gold to Yellow Tentacles | White & Teal Tips | Sustainably Grown by coralSLover®

Classification: High-End / Premium SPS-Style Stony Coral

Rainbow Galaxea (Galaxea sp.) is a stony LPS-style coral known for its long, fleshy tentacles, radial polyp structure, and spectacular color variability. Its tentacles, ranging from deep gold to bright yellow with white and teal tips, display a natural fluorescence under actinic and blue LED lighting, producing a dynamic “rainbow” effect. Color intensity is influenced by environmental factors such as light spectrum, water flow, nutrient levels, and tank placement.

This coral is slow-growing and encrusting, forming dense colonies over skeletal substrate. Each frag (½"–1") is carefully propagated in controlled aquaculture systems at coralSLover®, ensuring healthy skeletal growth, full polyp extension, and stable coloration. Rainbow Galaxea exhibits typical Galaxea traits, including moderately extended polyps during the day and diurnal contraction for protection, demonstrating both resilience and adaptability to a range of reef environments.

Scientific Notes:

  • Genus:Galaxea

  • Growth Form: Encrusting, with dense, long tentacles extending radially from each polyp

  • Coloration: Highly variable; tentacle and tip fluorescence shifts with light intensity and spectrum

  • Feeding: Photosynthetic via symbiotic zooxanthellae; can also benefit from supplemental microplankton or LPS-targeted feed

  • Environmental Tolerance: Prefers moderate to high light and flow; tolerates minor variations in water chemistry due to aquaculture acclimation

Sustainability & Provenance:
This Rainbow 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.

Frag Size: ½"–1", skeletal base supporting fully extended polyp clusters when open.

Great For: Advanced hobbyists, collectors, and reef enthusiasts seeking a rare, visually evolving coral centerpiece.

Free Shipping: When qualified.

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.
