Coelothrix irregularis

Coelothrix irregularis (Iridescent Wire Algae)
Iridescent Wire Algae is a stunning, fine-textured macroalgae with thin, wire-like branches in a deep reddish-purple base. Under full-spectrum lighting, its tips often glow with a bright bluish-green shimmer, giving it a truly unique appearance that changes depending on the angle of view. Think of it as a more delicate cousin to Chaetomorpha—compact, wiry, and perfect for adding shimmer and texture to your tank.

Care Guide:

• Light: Moderate to high (best color under full spectrum)

• Flow: Gentle to medium

• Placement: Rockwork or substrate in macroalgae-specific tanks

• Experience Level: Intermediate (slightly sensitive)

• Growth Rate: Moderate

• Benefits: Adds iridescent shimmer, unique wire-like structure, nutrient export

• Portion Size: dime-sized clump (not overly dense; often appears spindly and brown at first)
