“Red Fern” (Haliptilon sp.)

Red Fern, is a stunning calcareous red macroalga prized for its delicate, branching fern-like structure and vibrant pink-to-deep-red coloration. Its rigid, coral-like texture allows it to hold shape beautifully in both high- and moderate-flow systems, making it an eye-catching accent piece for display tanks and macroalgae aquascapes  

Red Fern adds instant contrast against green macros and live rock, creating a refined, ornamental look. Though slow-growing, it is hardy once established and maintains its vivid color under strong full-spectrum lighting.

Why Hobbyists Love It:

• Elegant, branching “fern” appearance
• Bold pink/red tones that pop in macroalgae displays
• Calcareous structure helps it hold shape and resist grazing
• Great for aquascaping nano and full-size macro tanks
