About this item

Red Coral Macroalgae

Red Coral Macroalgae (Peyssonnelia novae-hollandiae, provisionally) is one of the most extraordinary and visually deceptive specimens in the reef hobby — an Australian macroalgae that grows into a hard, sculptural, upright branching structure of deep crimson red that is virtually indistinguishable from living precious coral at first glance. Visitors to your tank will do a double take every time. What appears to be an elegant colony of rare red coral is in fact a macroalgae — photosynthetic, functional, and quietly working to export nitrates and phosphates while serving as a haven for copepods and microfauna throughout its complex branching architecture.

What makes Red Coral Macroalgae genuinely unlike anything else in the hobby is its physical structure. The thallus is hard and cartilaginous — firm to the touch, permanently holding its coral-like branching form regardless of flow or current. It does not wilt. It does not melt. It does not collapse under strong flow or go limp in low-nutrient systems the way softer macroalgae can. Place it in your aquascape and it stays exactly as positioned — a permanent, living crimson sculpture that grows slowly and organically over time into an increasingly impressive colony.

Sourced from Australian waters and essentially unknown in the reef hobby worldwide, Red Coral Macroalgae is a genuine first — a species that has never been commercially available before, and that delivers on every level a serious reef keeper could ask for. It is functional, structurally unique, visually stunning, and completely unlike anything else on the market.


Available Options

Starter Plant

  • One healthy Red Coral Macroalgae specimen (Peyssonnelia novae-hollandiae, provisionally) with established branching structure
  • Hard, cartilaginous form — arrives holding its shape and ready to place as an immediate display piece
  • A rare opportunity to own a species that has never been commercially available in the hobby before

Care Information

💡 Lighting
Low to Moderate — deep red coloration maintained best under moderate spectrum
🌊 Water Flow
Low to Moderate — holds form in any flow, tolerant and adaptable
📍 Placement
Rock-mounted — displays best elevated as a standalone centerpiece
⚙️ Care Level
Easy to Moderate — stable parameters recommended
📈 Growth Rate
Slow and controlled — grows organically into a more impressive colony over time
🧪 Nutrient Export
Moderate nitrate and phosphate uptake

Special Considerations

Red Coral Macroalgae is one of the most placement-flexible macroalgae available — its hard cartilaginous structure means it holds its form regardless of flow and does not require specific positioning to maintain its shape. Supplement with iron and iodine as part of a regular micronutrient dosing schedule to maintain rich crimson coloration. Keep away from aggressive herbivores including urchins, large tangs, and puffers which may graze on the thallus. As with all photosynthetic macroalgae, stable parameters and consistent lighting produce the best long-term results. Handle with care during placement — while robust, the branching tips can be brittle under significant pressure.

🔍 Aquarium Insights

  • The hard, cartilaginous branching structure is physically unique among macroalgae — it holds its coral-like form permanently, making it one of the most aquascape-friendly species available and a conversation piece in every system it inhabits
  • The complex branching architecture provides exceptional surface area and shelter for copepods, amphipods, and beneficial microfauna — one of the best macroalgae refuges available for supporting a thriving pod population
  • A species that has never been commercially available in the reef hobby — sourced from Australian waters, visually spectacular, and delivering real functional benefits every single day

Livestock Disclaimer

Due to natural variation, the specimen you receive may vary in branching structure, coloration, and overall form. Photographs are representative examples.

Individual specimens may display differences in branching density and crimson coloration intensity depending on lighting and tank conditions.

Size and appearance are provided as general guidelines and may vary slightly from the specimen received. As with all live animals, proper acclimation and a stable, established environment are essential for best results.
