Red Dragons Breath (Hayi Gracilaria) is one of the most striking macro algae available. Use rubber bands or glue to attach to rocks as this algae will not attach readily on its own. As it grows you can trim off the extra growth and use to feed your herbivore fish or simply toss out. This helps in removing excess nitrates and phosphates from you reef system and reduces nuisance algae growth.
