Blue Ochtodes is a highly sought-after macroalgae known for its vivid blue to violet iridescence under reef lighting. Although biologically a red macroalgae, its pigments reflect light in a way that produces its metallic blue coloration, making it one of the most eye-catching macroalgae used in marine aquascapes. It attaches itself to rock or substrate as it grows, slowly encrusting the area.
