Flat Blade Gracilaria Live Macro Algae Gracilaria tikvahiae

The Flat Blade Gracilaria tikvahiae plant, sometimes referred to as Red Spike Macro Algae, is an exceptionally beautiful macro algae. Between bright red and bergundy in hue and graced with sharp and pointy fronds, it adds a splash of color and texture to any refugium or saltwater aquarium. Flat Blade Gracilaria is a fast growing and hardy macro algae when kept under proper conditions. It is also great for nutrient export in saltwater aquarium systems. Additionally, it is prized by many herbivorous fish keepers (especially tangs) as a healthy live seaweed food. Pro Tip: Flat Blade Gracilaria can be grown out in the refugium and new growth can be trimmed and fed to herbivorous fish as a tasty treat.

*Please note that while we go to great lengths to treat, quarantine and remove any unwanted parasites, hitchhikers, and other organisms from our macro algae we do not guarantee that this item is completely and totally free of anything unwanted. This is because sometimes spores, eggs, etc can remain viable but not visible, despite our strict quarantine procedure. We strive to have the cleanest and highest quality macro algae on the market.
