Aquaculture Rainbow Cracker Blastomussa – RARE Collector’s LPS Coral
Scientific Name:Blastomussa merletti (Family: Mussidae)
Grown in the USA at coralSLover® 100% Aquaculture
Classification: High-End LPS Coral
Why It’s High-End:
• Displays rare, multi-color pigmentation rarely seen in aquacultured specimens
• Slow-growing, making each frag limited and valuable
• Exceptional color intensity under blue or actinic lighting
• Collector-grade morph of Blastomussa merletti rarely available in aquaculture
• One of the largest-headed species of this type, producing impressively full and vibrant polyps
The Rainbow Cracker Blastomussa is a true showpiece coral, highly prized among collectors for its extraordinary coloration and refined structure. Displaying a radiant mix of orange, teal, and light blue tones, this coral glows vividly under reef lighting—appearing almost gemstone-like as colors shift and intensify with angle and spectrum.
Unlike typical LPS species, Blastomussa merletti forms smaller, tightly packed individual polyps, each with a distinct fleshy head. These miniature polyps give the coral a unique texture and compact growth form, differentiating it from Blastomussa wellsi, which has larger, dome-shaped heads.
At coralSLover®, every Rainbow Cracker Blastomussa frag is 100% aquacultured in our controlled indoor systems. We never cut wild colonies—each coral is cultivated from a small starter polyp, ensuring optimal adaptation to home aquariums, exceptional coloration, and ethical, sustainable production.
Size & Growth
Each frag is offered as a single head (approximately 1"–1.5" when expanded) and can grow with proper care up to 2.5"+ this is one of the largest (heads) species of this type. Polyps expand significantly once acclimated, developing the characteristic inflated LPS texture.
Each frag is offered for sale as a single head up to 1”
Scientific Notes:
• Genus:Blastomussa
• Species:B. merletti
• Origin (Aquacultured Lineage): Derived from sustainable propagation of captive-grown colonies
• Natural Distribution: Western Pacific and Indo-Pacific reefs (wild ancestors)
• Growth Habit: Encrusting colonial with individual corallites forming separate skeletal cups
Care Level for Rainbow Cracker Blastomussa: Moderate
Lighting: Moderate PAR (80–150); coloration intensifies under blue LED or actinic spectrum
Flow: Low to moderate; gentle, indirect flow helps prevent tissue damage
Placement: Mid to lower levels of the aquarium; avoid direct flow and excessive light
Feeding: Benefits from occasional target feeding with coral foods or fine zooplankton
Great For:
Advanced hobbyists and collectors seeking a rare, aquacultured Blastomussa morph that combines intense coloration, compact form, and sustainable origins.
Each frag is offered for sale as a single head.
