Blue Hypnea (Hypnea pannosa) is an iridescent blue ornamental algae. Though similar in appearance to Ochtodes sp. algae from the Caribbean, this species originates from Micronesia and has slightly different morphology. Blue Hypnea grows in very dense, matted clumps that loosely anchor to coarse substrates. It is not a particularly fast growing algae so containing its growth is not difficult. We recommend moderate to high, full spectrum lighting for optimum coloration and growth.
